Schneider Electric TM221CE40R Modicon M221 40-IO Relay Ethernet Logic Controller

The Schneider Electric TM221CE40R is a Modicon M221 logic controller with 40 discrete I/O — 24 inputs and 16 relay outputs (2 A, 5-250 V AC or 5-125 V DC) — plus 2 analog inputs, powered from 100-240 V AC. It integrates Ethernet, RS232/RS485 serial, and USB ports, and supports up to 7 local or 14 remote I/O expansion modules.

Selection Notes

The 16-relay output block (2 A per point, 5-250 V AC or 5-125 V DC) lets the TM221CE40R switch mixed AC and DC loads directly — pilot lights, small AC contactor coils, 24 V DC valves — without external interposing relays, unlike a transistor-output M221 limited to DC loads. Its 100-240 V AC universal supply and built-in 24 V DC 250 mA sensor supply also remove the need for a separate control-power supply on a 40-point panel.

Applications

Mixed AC/DC discrete load switching on machine or panel control where a universal 100-240 V AC supply and integrated Ethernet networking are needed.
