Two-channel PID controller with analog outputs RP2

The RP2 device is designed to receive and convert signals from resistance thermocouples (RT), thermoelectric converters (PT) and sensors with a unified output signal of current (AT) and voltage (AN) into temperature values (or other physical quantities) and display them on built-in digital indicators with simultaneous control of the temperature of objects according to the proportional-integral-derivative (PID) law with a time delay.

RP2 can be used to control the performance of various technological processes in industry, agriculture and utilities (in processes where regulation is required). For example: in autoclaves, sterilizers, for controlling electric valves, etc.

The device automatically controls the state of the sensors, the finding of the measured temperature in the set measurement range.

Main functions of RP2:

• measurement of temperature, humidity, pressure (or other physical parameters)
  different objects on one or two channels using standard sensors:
  resistance thermoconverters [TC], thermoelectric converters [PT],
  sensors with a unified current output signal 0..5 mA, 0 (4) .. 20 mA [AT] and
  voltage 0..1V, 0..10V [AN];
• moisture measurement based on the psychrometric method using standard vehicles;
• display on the built-in LED digital indicators of the current and set
  temperature values in one of the channels;
• simultaneous display on built-in LED digital indicators
  current temperature values in two channels;
• regulation of temperature (humidity) of objects according to proportional-integral
  differential (PID) law on two channels;
• the ability to change the set temperature values (setpoints) for the PID controller by
  two channels;
• the ability to automatically adjust the coefficients of the PID controller;
• data exchange with a personal computer via RS-485 interface;
• light indication of the Operation mode of the Device, generation of the “Error” signal
