The Schneider TM241CEC24R is a compact logic controller from the Modicon M241 series, designed for versatile industrial automation tasks. This module integrates 24 discrete I/O points, combining relay and transistor outputs with Ethernet and CANopen connectivity. Engineers can rely on its robust feature set for efficient machine control.
Key Technical Specifications of the Schneider TM241CEC24R
The Schneider TM241CEC24R operates on a supply voltage of 100 to 240 V AC, making it suitable for global applications. It features 14 discrete inputs, eight of which are fast inputs compliant with IEC 61131-2 Type 1. The discrete outputs include six relay outputs and four transistor outputs, providing flexibility for different load types.
Input and Output Configuration
The inputs accept 24 V DC and can be configured as sink or source logic. Fast inputs achieve response times as low as 50 µs, ideal for high-speed counting. The relay outputs handle voltages up to 250 V AC and 125 V DC, with a current rating of 2 A. Transistor outputs deliver 24 V DC and support frequencies up to 100 kHz for pulse train output (PTO) mode.
- Discrete input voltage: 24 V DC
- Fast input response time: 50 µs
- Relay output current: 2 A
- Transistor output frequency: up to 100 kHz
Communication Capabilities
The controller integrates multiple communication interfaces. It includes an Ethernet port supporting 10/100 Mbit/s with protocols like Modbus TCP, EtherNet/IP, and OPC UA. The CANopen interface allows master functionality with up to 63 slaves. Additionally, two serial links provide RS232 and RS485 connectivity for legacy devices.
Furthermore, the USB port enables easy programming and data transfer. The controller also supports web server functions for remote monitoring.
Performance and Memory
Execution time for 1 KInstruction is 0.3 ms for event tasks and 0.7 ms for other instructions. It has 64 MB of RAM and 128 MB of flash memory for user program backup. An optional SD card supports up to 16 GB for data storage. The real-time clock maintains accuracy within 60 seconds per month.
Applications and Best Practices
The Schneider TM241CEC24R is well-suited for small to medium automation systems requiring integrated I/O and networking. Engineers should ensure proper mounting on a TH35 rail and maintain ambient temperatures within -10 to 55 °C. For reliable operation, use shielded cables for fast I/O and follow grounding guidelines.
