Inputs are sink or source, 4.7 kΩ impedance, and accept A/B quadrature or pulse/direction encoder signals on the fast inputs (up to 200 kHz in single-phase HSC mode). The sensor supply provides 400 mA at 24 VDC, enough for a small cabinet of proximity switches. Cycle time runs 10 ms for 16 EtherNet/IP nodes and 64 ms over 64 Modbus TCP connections – pair that with the real-time clock and 128 MB flash backup to hold a machine sequence through a power loss. Built-in OPC UA server, EtherNet/IP originator, and Modbus TCP server mean you can talk to a SCADA or another controller without an add-on module. The web server serves WebVisu HMI pages directly. ## Supply & serial line discipline The serial port requires its own 5 V supply under 200 mA – that is not drawn from the main 24 V sensor bus. Use an isolated DC-DC converter if the main PSU lacks a 5 V rail. Ethernet ports are 10BASE-T/100BASE-TX (one copper). Use shielded cable for the 2 kV common-mode surge on the power lines. Mounting: TH35-15 or TH35-7.5 DIN rail, or panel with fixing kit. Dimensions 95 mm deep, 190 mm wide, 90 mm high – the depth is the critical clearance behind the door on shallow enclosures. ## Lifecycle, compliance & sourcing posture Compliance covers UL 508, CSA C22.2, IEC 61131-2, and marine certifications (LR, ABS, DNV, GL). Pollution degree 2, surge immunity per IEC 61000-4-5. The CE marking is present on the unit. Memory: 64 MB RAM for runtime, 128 MB flash for user program backup. Battery (BR2032, non-rechargeable) backs the RTC for 2 years at 25 °C. Clock drift ≤60 s/month.","metaTitle":"Schneider TM241CE40R Modicon M241 PLC, 40 I/O, Relay/Transis","metaDescription":"Active Modicon M241 PLC with 40 mixed I/O (relay + transistor), 24 VDC sensor supply, 2 Ethernet ports, OPC UA server.
