Description
The listed TM221C24R, TM221CE40R, TWDFCW30K, TCSMCNAM3M002P, TWDFCW30M, TWDFCW50K are Schneider Electric Modicon M221 (Easy M221) Programmable Logic Controllers and SoMachine / EcoStruxure Machine Expert – Basic (formerly SoMachine Basic) accessories.
- TM221C24R → Modicon M221 Controller, 24 I/O (14 × 24V DC Sink/Source Inputs + 10 × Relay Outputs 2A/point), No embedded analog, 1 × RJ45 Ethernet port (Modbus TCP + programming), 1 × Mini-USB port (programming / HMI link), SD Card slot (for backup/log), Spring terminal (C = spring clamp; S = screw — C24R = spring), Rated supply 100–240V AC or 24V DC? Actually TM221C24R = AC supply (100–240V AC) — R suffix = Relay outputs; if DC supply version it would be TM221C24DR (24V DC in) — check: Schneider naming: TM221 C 24 R → C=Spring terminal, 24=I/O count, R=Relay outputs — Power: AC supply (85–264V AC) standard on non-D versions; DC supply = add D before R e.g. TM221CD24R = 24V DC in, spring, 24 I/O, relay out).
- TM221CE40R → M221 40 I/O version (24 DI + 16 DO Relay — or 24 DI + 16 Relay typical for CE40R — actually CE40R = 40 I/O: 24 × 24V DC inputs + 16 × Relay outputs 2A, Spring terminal, AC supply, Ethernet + USB, SD slot — expanded I/O count over C24R). “E” in some regions denotes Ethernet included (all M221 have Ethernet — E just regional packaging diff; CE40R = 40 I/O relay AC supply spring).
- TWDFCW30K / TWDFCW30M / TWDFCW50K → Programming / PC Connection Cables for Schneider PLCs (Twido / M221 / M241 via USB) — TWDFCW30K = USB A to Mini-B (for M221 USB port — same as printer cable! Actually TWDFCW30K = USB cable type A-B for Twido/M221/M241 — length 3m “K” maybe region code; TWDFCW30M = 3m; TWDFCW50K = 5m). These are standard USB 2.0 A-to-Mini-B cables — any quality Mini-B USB cable works but Schneider p/n ensures spec compliance.
- TCSMCNAM3M002P → **Serial (RS-232/RS-485) Communication Cable — Schneider Modicon / Twido / M221 — Mini-DIN to DB9 or terminal block? Actually TCSMCNAM3M002P = Modicon to PC serial cable (RJ45? Wait: TCSMCNAM3M002P = TSXPCX1031 (legacy) replacement — “CNAM3M002P” = CANopen? No — check: Schneider cable for M221 serial port (if used) — M221 has RJ45 Modbus RTU port (Serial) + Ethernet + USB. TCSMCNAM3M002P is the RJ45 to DB9 Female (Straight through for Modbus RTU / ASCII to PC COM port or HMI) — 2m length. Used to connect M221 Serial RJ45 port → PC RS-232 (DB9) or 3rd party device.
The Modicon M221 is part of the Easy Logic Controller range (successor to Twido TWDLCAE series in small apps) — programmed with EcoStruxure Machine Expert – Basic (free download from Schneider — formerly SoMachine Basic). It targets stand-alone machines, small packaging, pump/fan control — up to 240 I/O with expansion (TM2… expansion modules — TM2AMI2LT / TM2DDI… etc. — M221 supports up to 7 TM2 expansion modules on right-side bus).
Key Features (TM221C24R)
- I/O: 14 × 24V DC Digital Inputs (Sink/Source — 10k–30V DC range, 2 high-speed counter inputs capable up to 100 kHz on I0/I1 typically), 10 × Relay Outputs (NO — 2A resistive / 250V AC or 30V DC — common per 4 pts typically: Out 0–3 = COM0; Out 4–7 = COM1; Out 8–9 share COM2? Check manual — C24R has 3 commons for 10 relay outputs)
- Communication: 1 × Ethernet RJ45 (Modbus TCP, Machine Expert programming), 1 × Serial RJ45 (Modbus RTU Master/Slave ASCII), 1 × Mini-USB (programming & local HMI link — no driver install needed on Win10+)
- Memory: 16 MB program + data (symbolic programming supported), recipe, data logging to SD
- SD Card Slot: For program backup, data logging, firmware update (SDHC up to 32GB — Schneider recommends specific cards like TSXSAC64K / TSXSAC128K — but standard SDHC often works)
- Expansion: Up to 7 TM2 series I/O modules (analog, more DI/DO, thermocouple, etc.) on right-side expansion bus
- Country of Origin: France / China (Schneider Electric)
