Modular Multi-Channel High Performance Temperature Controllers TMH Series

Product Overview

The TMH Series modular multi-channel high-performance temperature controllers offer a versatile solution for precise temperature management across multiple channels. Designed for industrial applications requiring simultaneous control of 2 or 4 input/output channels, these controllers feature a high-speed sampling rate of 50 ms and an impressive measurement accuracy of ±0.3%. The TMH Series supports simultaneous heating and cooling control, making it ideal for complex temperature regulation tasks. One of the key benefits of the TMH Series is its modular design, which allows for easy expansion. Users can connect up to 32 units, managing as many as 128 channels without the need for additional wiring for power or communication. The system’s flexibility extends further with the ability to connect up to 16 communication modules to a master device, supporting a total of 1,024 control channels. Additionally, the TMH Series offers various option modules, including analog input/output modules, digital input/alarm output modules, and CT input modules. Communication modules are available for PLC ladder-less communication (RS422/485) and Ethernet. The system supports parameter configuration and status monitoring via PC connections using USB, RS422/RS485, or Ethernet.
