SCHNEIDER ELECTRIC MODICON TM3BCSL
SCHNEIDER ELECTRIC MODICON TM3BCSL is a TM3 bus coupler module with Modbus Serial Line interface for distributed TM3 I/O island, compatible with Modicon M221, M241, M251 and M262 PLC controllers. This Modbus serial line bus coupler connects TM3 digital and analog I/O modules as a remote I/O station and communicates with master PLC via RS485 Modbus SL fieldbus. The Modbus serial line bus coupler features two isolated RJ45 RS485 ports for daisy-chain wiring and one mini-USB port for local configuration and commissioning. The Modbus serial line bus coupler supports up to 448 digital I/O and 112 analog I/O points with baud rate range from 1.2 kbit/s to 112.2 kbit/s. The Modbus serial line bus coupler serves as core distributed I/O spare part for packaging, material handling and machinery automation cabinet overhaul and remote I/O retrofit.

This TM3BCSL unit is DIN rail mount, powered by 24VDC auxiliary supply with IP20 protection class. TM3BCSL has embedded web server, built-in diagnostic LEDs and watchdog function for communication and module fault detection. TM3BCSL is programmed by EcoStruxure Machine Expert software, compliant with IEC 61131-2, UL and CE industrial standards. TM3BCSL is widely used for machine local distributed I/O expansion in factory automation and process auxiliary control systems.

As compact distributed I/O communication hardware, this SCHNEIDER ELECTRIC bus coupler reduces field wiring and enables flexible I/O placement near machine actuators and sensors. SCHNEIDER MODICON TM3 series spare parts include TM3BCSL bus couplers, digital input/output modules, analog modules, terminal blocks and bus extension cables for remote I/O station maintenance. SCHNEIDER bus coupler modules are trusted replacement units for legacy Modicon M2xx PLC distributed I/O systems.
