The Schneider TM221ME16TG is a Book-format Modicon M221 logic controller with embedded Ethernet. It provides 16 embedded digital I/O points, consisting of 8 digital inputs and 8 transistor outputs, and operates from a 24 VDC power supply.
The TG suffix identifies a specific transistor-output and terminal configuration. Output polarity, removable-terminal design and field-wiring arrangement must be confirmed from the exact controller nameplate, datasheet and installed machine wiring.
This controller is suitable for modular machinery requiring compact panel width, Ethernet communication, serial connectivity, solid-state outputs and expansion through the TM3 I/O platform.

The TM221ME16TG is suitable for packaging machines, conveyors, modular machine sections, compact control panels, assembly equipment, pump and fan systems and general industrial automation.
The transistor outputs are suitable for compatible solid-state control loads and frequent switching. Output polarity, common wiring, terminal type, current limit and protective components must be verified before installation.
The embedded Ethernet port can connect the controller to compatible HMI, PLC and supervisory systems. Confirm network addressing, Modbus TCP functions, firmware and machine-project compatibility.
Verify the complete TM221ME16TG reference. The TG suffix must not be omitted because it identifies a particular output and terminal configuration.
TM221ME16T may use a different terminal arrangement, while TM221ME16R uses relay outputs. These models should not be considered automatically mechanically or electrically interchangeable.
Before replacement, back up the EcoStruxure Machine Expert - Basic project, Ethernet settings, serial parameters, I/O mapping, high-speed functions, firmware, cartridges and TM3 expansion arrangement.
Related Book-format Ethernet controllers include TM221ME16T, TM221ME16R and TM221ME32TK.
TM221CE16T and TM221CE16U are compact Ethernet controllers with different enclosure dimensions, terminal layouts and embedded I/O distributions.
Please provide the complete controller nameplate, output-wiring diagram, terminal type, power supply, connected loads, Ethernet configuration, serial settings and expansion-module list.
Output polarity, terminal compatibility, firmware, software project, cartridge configuration, product condition, testing requirements, availability and delivery time must be confirmed before quotation.
