The Schneider TM221CE16T is a compact Modicon M221 logic controller with 16 embedded digital I/O points, including 9 digital inputs and 7 PNP transistor outputs. It operates from a 24 VDC power supply and includes an embedded Ethernet port.
The solid-state PNP output configuration is suitable for modern 24 VDC machine-control systems requiring faster and more frequent switching than a relay-output controller. Typical connected devices include compatible solenoid valves, interposing relays, indicator circuits and electronic control inputs.
The complete TM221CE16T commercial reference must be retained because the final T identifies a transistor-output configuration. It must not be confused with the relay-output TM221CE16R or the NPN transistor-output TM221CE16U.

The TM221CE16T is suitable for compact packaging machines, labeling equipment, conveyors, assembly machines, small positioning systems and automated material-handling equipment using 24 VDC control circuits.
PNP transistor outputs are generally used with sourcing-output wiring conventions. The connected load voltage, current, common wiring, leakage current and protective devices must be verified before commissioning.
Applications using high-speed pulse outputs must be checked against the required pulse frequency, output channel, motion function and connected drive or stepper interface.
Verify that the installed controller is TM221CE16T and not TM221CE16U. The T and U output configurations use different source or sink wiring and are not direct electrical replacements.
TM221C16T has similar embedded I/O but does not include the embedded Ethernet port. TM221ME16T uses a Book-format enclosure with 8 inputs and 8 outputs rather than the compact 9-input and 7-output arrangement.
Back up the controller application, IP address, Ethernet services, serial settings, pulse-output configuration, I/O mapping and expansion-module configuration before replacement.
Related models include TM221CE16R with relay outputs, TM221CE16U with NPN transistor outputs, TM221CE24T with 24 embedded I/O and TM221CE40T with 40 embedded I/O.
TM221ME16T is the related Book-format Ethernet controller with 8 digital inputs and 8 PNP transistor outputs.
Please provide the full existing model, power-supply voltage, transistor-output wiring, connected load current, Ethernet configuration, serial communication settings and required pulse functions.
Firmware, software-project compatibility, TM3 expansion modules, cartridges, product condition, testing requirements, availability and delivery time must be confirmed before quotation.
