The SMC ITV2030-012N is an electro-pneumatic regulator designed for industrial compressed-air systems that require pressure to be controlled by an electrical signal rather than by manual adjustment. It is part of SMC’s ITV1000/2000/3000 Series, a family developed for stepless control of air pressure in proportion to an electric signal. In practical automation work, this means the regulator can receive an analog command from a PLC, motion controller, or other industrial control device and convert that command into a stable output pressure. That operating concept makes the ITV2030-012N suitable for packaging machines, assembly equipment, test benches, inspection systems, and general factory automation where pressure repeatability matters.
The specific model code is important because it identifies more than just the series. Distributor decoding for ITV2030-012N shows that it is a 2000-size regulator in the 0.005 to 0.5 MPa pressure range, powered by 24 VDC, using a 4 to 20 mA DC sink-type input signal, and providing an analog 1 to 5 VDC monitor output. The absence of bracket and cable suffix options in this code indicates a relatively standard body configuration compared with models that include bracket or long-cable options. That makes the ITV2030-012N a useful baseline configuration for machine builders who want an electronically controlled regulator without extra mounting or connector accessories specified in the base code.
One of the strongest commercial reasons to use this model is that it allows pneumatic pressure to become part of the machine’s control logic. In conventional systems, an operator sets pressure manually and adjusts it again whenever process conditions change. That is inefficient when a machine handles multiple product sizes, different gripping forces, or several process stages with different pressure requirements. The ITV2030-012N avoids that limitation by allowing pressure to be commanded electronically. SMC’s ITV series documentation also describes the family as compact, lightweight, and IP65 equivalent, which supports its use in real industrial machine layouts where space is limited and environmental protection is still required.

These model and series specifications are supported by SMC ITV catalog data and model-specific distributor references for ITV2030-012N. The ITV family documentation lists the ITV2000 class with IP65-equivalent protection, 0 to 50°C operating temperature, and an approximate unit weight of 350 g. Model-specific catalog decoding identifies the 24 VDC supply, 4 to 20 mA sink-type input, 1 to 5 VDC monitor output, and 0.5 MPa range for the ITV2030-012N.
Product Weight
For installation, shipping, and mechanical layout planning, the SMC ITV2030-012N has an approximate product weight of 350 g without options, based on SMC’s ITV2000-series specification. This figure is not just a logistics detail. In actual machine design, regulator weight affects bracket sizing, manifold load, moving-frame design, and control-panel layout. A regulator that offers closed-loop electro-pneumatic control while remaining in the mid-hundreds-of-grams range is easier to mount in compact equipment than a bulkier control assembly.
The weight also reflects the design intent of the ITV family. SMC and distributor references consistently position the series as compact and lightweight, which is relevant because electronic regulators are often selected for machines where functional density matters. In other words, the ITV2030-012N adds programmable pressure control without imposing the installation penalty of a large external regulator-and-transducer arrangement. For OEMs building space-constrained equipment, that is a practical advantage.
Working Principle
The ITV2030-012N works by converting an electrical input signal into a proportional output pressure. In this specific model, the command is a 4 to 20 mA DC sink-type current signal. The internal control electronics interpret that signal as a target pressure value, compare it with the actual downstream pressure measured by the regulator, and continuously adjust the valve section until the output pressure matches the command. This is the core operating principle of the ITV family, which SMC describes as air-pressure control proportional to an electric signal.
That closed-loop control method is why the ITV2030-012N is useful in automated equipment. A manual regulator can set pressure, but it cannot automatically follow process changes. The ITV2030-012N can. If a machine needs one pressure during product positioning, another during clamping, and another during blowing or testing, those changes can be handled directly by the control system rather than by an operator. This reduces setup time, improves repeatability, and makes process behavior easier to standardize across shifts and production batches.
The model also provides an analog 1 to 5 VDC monitor output, which means the control system can observe regulator behavior as well as command it. That supports a better automation architecture because pressure control becomes both controllable and monitorable. In practice, this can be used for diagnostics, alarm logic, process validation, or recipe confirmation. For machines where pneumatic force directly affects quality, that monitor signal adds real engineering value.
Performance Characteristics
SMC’s ITV-series specifications give the technical basis for why this regulator is suitable for precision pneumatic work. The family catalog lists linearity of ±1% F.S. or less, hysteresis of 0.5% F.S. or less, repeatability of ±0.5% F.S. or less, sensitivity of 0.2% F.S. or less, and temperature characteristics of ±0.12% F.S./°C or less. These are the numbers that matter when evaluating whether an electro-pneumatic regulator is appropriate for pressure-sensitive industrial applications.
Those figures translate into practical benefits. Good linearity means the output pressure follows the command with predictable proportional behavior. Low hysteresis means there is limited difference between increasing and decreasing response. Good repeatability means the same command can produce nearly the same pressure repeatedly over successive cycles. In packaging, assembly, or test applications, those characteristics are more important than generic marketing language because they determine whether the machine behaves consistently enough for production use.
Typical Applications
| Application Area | Typical Use of ITV2030-012N |
|---|---|
| Packaging Machinery | Controls sealing pressure, blowing pressure, and hold-down force |
| Assembly Equipment | Regulates clamping and pressing pressure automatically |
| Inspection and Test Systems | Provides stable programmable pressure for repeatable testing |
| Pneumatic Handling | Adjusts gripping pressure according to product requirement |
| OEM Machine Building | Integrates pressure control into PLC-based automation logic |
| General Factory Automation | Replaces manual regulator setting with analog signal control |
These applications align directly with the stated function of the ITV family as an electro-pneumatic regulator for proportional pressure control. The current-input configuration of the ITV2030-012N is particularly useful in industrial control environments where 4 to 20 mA remains a standard analog interface because of its noise resistance and long-distance signal reliability. That makes this model a sensible choice for equipment with conventional industrial I/O architecture.
Why Choose the ITV2030-012N
From a controls perspective, the ITV2030-012N is attractive because it uses a 4 to 20 mA current input, which is still one of the most common analog-control standards in industrial automation. Current signals are generally less susceptible to signal degradation over longer cable runs than low-voltage analog signals, which can make this configuration preferable in larger machines or noisier control environments. The included 1 to 5 VDC monitor output also provides flexibility for supervision and feedback integration.
From a mechanical and commercial perspective, the regulator combines a 0.5 MPa working range, compact ITV2000 body size, IP65-equivalent protection, and approximate 350 g weight. Those factors make it practical for both new machine builds and replacement projects. The fact that the model appears through multiple established distributors also suggests it is a standard market configuration rather than an obscure special-order variant.
Conclusion
The SMC ITV2030-012N is a compact ITV2000-series electro-pneumatic regulator intended for industrial systems that need accurate air-pressure control through an electrical signal. Based on SMC series documentation and model-specific references, it is a 0.005 to 0.5 MPa regulator with 24 VDC power, 4 to 20 mA DC sink-type input, 1 to 5 VDC analog monitor output, IP65-equivalent protection, and an approximate product weight of 350 g without options.
For machine builders, integrators, and industrial users, this model is a sound choice when pneumatic pressure must be controlled as part of the automation strategy instead of being left as a fixed manual setting. Its strongest value is in applications where repeatability, compactness, analog-current compatibility, and practical industrial durability are required.
