6, 2 RS485 communication protocol 


Channels: 4 channels


Normally, the CM-4TM needs to equip 1 pc USB to RS485 cable.


CM-4TM Temperature controller module achieves high-speed sampling (100ms), side connection can expand up to 31 modules, and doesn't require additional power supply and communication lines, and communicates with PC through RS485.

In addition, various convenient and concise functions are available to achieve accurate temperature control.


* Up to 124 simultaneous controls 


* Insulation strength per channel- Dielectric strength 1000VAC


* Up to 31 modules (124 channels /62 channels) are connected, and the used expansion modules don't require additional communication and power supply.


* High-speed sampling period (TM4:100ms)


* Heating/cooling control at the same time


* Monitor heater status with current transformer (CT)


* Communication with PC (Modbus RTU) via RS485:


*Wiring and maintenance of connector wiring: Sensor input interface, control output interface, power supply/communication connector


* Multi-channel input/multiple range
