M74 SERIES

M74 SERIES

4 CH modular type PID controller

High reliability with the complete insulation and efficient space arrangement with the compact structure. Simple maintenance and repair with the structure of separating base from the main body. Unnecessary communication between modules and power wiring through extension connectors. Easy and convenient parameter setting (on-site) by using device integrated management program.

  • Ultra compact size (65%Compared to other brand)
  • Easy and convenient parameter setting with the console
  • RS485 communication with fully independent isolation structure (PC/TL-Link, Modbus-ASCII/RTU)
  • Simple maintenance and repair by separate structure of main body and base
  • Support electronic address and communication setting
  • Compete insulation structure between each input and input/output (Withstanding voltage 1,000V AC or higher)
  • Providing device integrated management program to ease remote monitoring and setting
  • Support free output port setting to simultaneously control transmission output and heating/cooling
  • Unnecessary communication between modules and power wiring through extension connectors
