Schneider TM221ME16T Modicon M221 Book Format 16 I/O PNP Transistor Logic Controller 24VDC with Ethernet
| Place of Origin | Germany |
| Brand Name | Schneider Electric |
| Model Number | TM221ME16T |
Product Overview
The Schneider TM221ME16T 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 supply.
The narrow Book-format construction is designed for modular control-panel layouts where horizontal space and terminal arrangement differ from the standard compact TM221CE controllers. It is suitable for machines requiring Ethernet communication, serial connectivity and TM3 expansion in a modular controller structure.
The T output code identifies a transistor-output version. The exact PNP wiring, terminal configuration and connected-load requirements should be verified against the controller documentation and machine wiring diagram.

Compatible System and Applications
The TM221ME16T is suitable for packaging machinery, compact conveyors, modular machine panels, assembly systems, small positioning applications and general OEM equipment.
The Book-format enclosure is useful where the existing machine is designed around the TM221M or TM221ME mechanical platform. Cabinet width, terminal location, expansion-module arrangement and wiring access should be checked before replacement.
The embedded Ethernet port supports integration with compatible HMI, PLC and supervisory equipment. Confirm Modbus TCP addressing, network services and firmware compatibility with the existing controller project.
Maintenance and Replacement Notes
Verify the complete TM221ME16T commercial reference. TM221M16T is the non-Ethernet Book-format version, while TM221CE16T is a compact Ethernet version with a different 9-input and 7-output I/O arrangement.
TM221ME16R uses relay outputs. TM221ME16TG is a different transistor and terminal configuration and should not be assumed to be mechanically or electrically identical.
Before replacement, back up the machine project, Ethernet settings, serial configuration, I/O mapping, high-speed functions, firmware and connected TM3 module arrangement.
Related Models
Related Book-format Ethernet references include TM221ME16R, TM221ME16TG and TM221ME32TK.
Related compact Ethernet controllers include TM221CE16T and TM221CE24T, but their mechanical format, terminal layout and embedded I/O distribution are different.
Inquiry and Supply Notes
Please provide the exact installed model, controller and field power supply, transistor-output wiring, terminal type, Ethernet configuration, serial protocol and expansion-module list.
Firmware, software-project compatibility, TMC2 cartridge configuration, product condition, functional testing, regional availability and delivery time must be confirmed before quotation.
