TRM202 is a 2-channel process controller from akYtec for on-off or proportional control, which features an RS485 interface, 2 configurable analog inputs and 2 optional outputs (relay, 4-20 mA) and is available in wall or panel mount enclosure

TRM202 is a 2-channel process controller available in two enclosures: for wall or for panel mounting. Beside the on-off control, the TRM202 can also implement proportional control. This controller has two analog inputs and two outputs on board. The inputs are configurable and can be set for standard current/voltage signals (0-1 V, 4-20 mA, etc.) or for different standard TC/RTD signals, what allows this device to measure, display and control different physical process variables such as pressure, temperature, humidity, etc. The optional outputs (relay, 4-20 mA) and RS485 interface provide particular flexibility when using this controller for creating automatic control and regulation systems of various processes in different areas of industry, agriculture, and utilities.

Functions and features:

Measuring the process value and its transformation according to the sensor type
Displaying the process values and configuration parameters on two 4-digit LED displays
Adjusting measured parameters and fixing errors of the converters
Displaying measurement results on a 4-digit LED screen
Creating an alarm signal in case of converters’ failure, displaying cause on the LED-screen and sending alarm message to external device if necessary
Creating signals for controlling external actuating mechanisms and devices according to preset instructions for adjustment
Displaying preset adjustment instructions on a LED screen
