TRM212 PID controller

TRM212 is a stand-alone PID controller available in two enclosures: for wall or for panel mounting. A special feature of this process controller is the ability to control analog- or 3-step control valves. Depending on the device variant, you can implement it whether with an analog output or with two digital outputs. The TRM212 has two 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, 0-10 V) 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 process values and configuration parameters on two 4-digit LED displays
• Scaling and filtering the input signal
• Signal correction, square root function
• Calculation of the sum or the ratio of the signals, the difference or the root of the difference between two signals
• PID control of the measured or calculated value with an analog or three-step control valves
• Weather compensation control (remote setpoint adjustment in accordance with an external parameter)
• Autotuning function
• Stand-alone control
• Manual control
• Network control (RS485 interface) with akYtec, Modbus RTU and Modbus ASCII protocols as a Slave
• Alarm output
• Sensor / input error and Loop Break Alarm detection
• Error indication
• Remote start/stop using digital input
• Configuration via the functional keys
