SEM MT30R4-37 Industrial Control Module

This compact control module delivers precise automation capabilities for demanding industrial environments. Originally designed for process monitoring and machine control applications, it handles critical tasks in manufacturing lines, energy infrastructure, and remote monitoring systems.

Field technicians particularly appreciate its performance in harsh conditions – one maintenance engineer recently reported keeping a water treatment facility’s pump system operational during extreme winter conditions down to -32°C. We commonly supply this module for legacy automation systems in oil & gas facilities and older generation manufacturing equipment. Compatible with Modbus RTU protocols through its RS485 interface, it integrates smoothly with SCADA systems using standard communication protocols.

What sets this module apart is its dual-interface design allowing simultaneous Ethernet and serial communication. The IP67-rated enclosure resists dust ingress and temporary water immersion, making it suitable for outdoor installations. Four relay outputs handle inductive loads up to 5A, while the eight optically-isolated digital inputs accept voltage ranges from 12-24V DC. Redundant power input terminals provide additional reliability in critical control loops.

While compact in size, this module maintains industrial-grade durability through its reinforced ABS housing and conformal-coated PCB. Users benefit from its straightforward DIN rail mounting and tool-less wiring terminals. The LED status indicators simplify troubleshooting, showing communication activity and power status at a glance. Many customers choose this as a direct replacement for obsolete PLC modules in legacy systems where modernization isn’t cost-effective.
