Two-channel PID controller for control of gate valves and three-position valves RP2-Z

A two-channel PID controller for controlling gate valves and three-position valves (RP2-З) is designed to receive and convert signals from resistance thermocouples (RT), thermoelectric converters (PT) and sensors with a unified current output signal (AT) and voltage (AH), in temperature values (or other physical quantities) and displaying them on the built-in digital indicators with simultaneous regulation of the temperature of objects according to the proportional-integral-differential (PID) law in two channels.

RP2-Z allows you to control a shut-off and control valve (KZR) or a three-way valve without taking into account its position according to the PID or pulse law in two channels.

a two-channel regulator automatically controls the state of the sensors, the finding of the measured temperature in the set measurement range

The main functions of RP2-Z:

• 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] on two channels;
• display on the built-in LED digital indicators of the current and set values
  temperature in two channels;
• production of a weather-dependent regulator with two outputs (automatic change of the preset temperature of the first channel according to the temperature of the second channel)
• humidity control (psychrometric) method;
• it is possible to manufacture devices for working with digital humidity_sensors (when ordering, indicate the DVT input);
• regulation of a physical quantity by proportional-integral
  differential (PID) law on two channels;
• control of the shut-off and control valve (KZR) or three-way valve without taking into account it
  positions according to PID or impulse law on two channels;
• maintaining the temperature of the object according to the proportional-integral-differential (PID) law in
  system "heater-refrigerator" in two channels;
• the ability to change the set temperature values (setpoints) for the PID controller;
• the ability to automatically adjust the coefficients of the PID controller;
• data exchange with a personal computer via the interface RS-485;
• the device has two four-digit seven-segment displays;
• two power modifications: from an alternating voltage network with a nominal value of 220V or from a constant voltage source with a nominal value of 12..24V;
• light indication of the operating mode of the device, formation of the “Error” signal.
