TRM202 2-channel controller

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
• Scaling and filtering the input signal
• Signal correction, square root function
• Calculation of the difference between two signals
• Independent on-off control of two process variables or three-step control of one process variable
• Network control (RS485 interface) with akYtec, Modbus RTU and Modbus ASCII protocols as a Slave
• Signal retransmission using analog output 4-20 mA
• Alarm output
• Sensor / input error detection
• Error indication
• Configuration via the functional keys
