Two-Channel PID Controller with Analog Outputs RP2

The RP2 device is designed to receive and convert signals coming from resistance temperature detectors (RTDs), thermoelectric converters (TCs), and sensors with a standardized current output signal (AT) and voltage output (AN), into temperature values (or other physical quantities), and to display them on built-in digital indicators while simultaneously regulating the temperature of objects by a proportional-integral-derivative (PID) law with time delay.

RP2 can be used for controlling various technological processes in industry, agriculture, and communal services (in processes requiring regulation). For example, in autoclaves, sterilizers, for controlling electric drives, and more.

The device automatically monitors the condition of sensors and ensures that the measured temperature is within the set measurement range.

Main functions of RP2:

• Measurement of temperature, humidity, pressure (or other physical parameters) of various objects on one or two channels using standard sensors:
  Resistance temperature detectors [RTD], thermoelectric converters [TC],
  Sensors with standardized output current signals 0..5 mA, 0(4)..20 mA [AT], and
  Voltage 0..1V, 0..10V [AN];
• Humidity measurement based on the psychrometric method using standard RTDs;
• Display of current and set temperature values on built-in LED digital indicators for one channel;
• Simultaneous display of current temperature values on built-in LED digital indicators for two channels;
• Temperature (humidity) regulation of objects by proportional-integral-derivative (PID) law on two channels;
• Ability to change set temperature values (setpoints) for the PID controller on two channels;
• Possibility of automatic PID controller coefficient tuning;
• Data exchange with a personal computer via RS-485 interface;
• Light indication of the device's operating mode, generation of "Error" signals;
