TMH Series

The TMH series modular multi-channel high performance temperature controllers are capable of controlling up to 2 or 4 channels of input/output simultaneously, with 50 ms high-speed sampling cycle, ±0.3% measurement accuracy, and simultaneous heating and cooling control function. The control channels can be expanded without additional wiring for power or communication. The control modules can be expanded up to 32 units and 128 channels. With each communication module, the units can be expanded up to 32 units (16 control modules & 16 option modules). Up to 16 communication modules can be connected to a master device for a total of 1,024 control channels. The modular design allows flexible expansion depending on user requirements, with various option modules available including analog input/output modules, digital input / alarm output modules, CT input modules, and communication modules. Parameter configuration and status monitoring is available with PCs using USB or RS485 communication connection.

Multi-Channel Input/Output Control (2-Channel/4-Channel)

The control modules (TMH2/4) can control up to 2 or 4 channels of input and outputs, performing as 4 separate temperature controllers.

Various Option Modules for Flexible Application

The TMH series modular temperature controllers allow users to expand units and functions to fit application requirements. Four different option models are available: analog input/output module, digital input/alarm output module, CT input module, and communication module.

Modular Expansion Up to 32 Units

Up to 32 units can be connected with expansion connectors without requiring wiring for individual power supply and communication.

50 ms High-Speed Sampling and ±0.3% Measurement Accuracy

The temperature controllers feature high-speed sampling rate of 50 ms and ±0.3% measurement accuracy while simultaneously controlling 4 separate channels. (Simultaneous 4-channel control)

Simultaneous Heating & Cooling Control

The temperature controllers can simultaneously control heating and cooling for efficient and optimal temperature control

Switch Between Current Output and SSR Drive Output

Users can select current output and SSR drive output using parameter settings in the DAQMaster software.

Body and Base Terminal Detachable

The main body unit of TMH series is detachable from the base terminal, allowing easier maintenance. The power and communication are all connected by the connectors on the base terminal, and will not be affected when a single unit needs to be checked or replaced.
