Two-position Single-channel Controller RD1

The two-position single-channel controller RD1 1UV/1R performs the following functions: measuring temperature, humidity, pressure (or other physical parameters) of various media and objects.

Used in furnaces of different purposes, drying cabinets, refrigeration equipment, as well as in other areas of activity and for measuring other physical quantities using sensors with standardized output signals.
The device performs two-position regulation of the input physical quantity on two channels, automatically monitors the condition of input sensors, detects measured input quantities outside the set measurement range, verifies correct parameter entry and carries out device calibration.

Main functions:

• Works with standard sensors:
  thermoresistors [TO],
  thermoelectric converters [PT],
  thermocouples (THK, THA, THJ, etc.),
  sensors with standardized current output signals 0..5 mA, 0 (4)..20 mA [AT] and voltage 0..1 V, 0..10 V [AN]
• Displays current measured parameter values on built-in LED digital indicators;
• Measures humidity based on the psychrometric method;
• Regulates object temperature by two-position control;
• Regulates object temperature by three-position control with one channel;
• Operates in pulse regulator mode (with the ability to set pulse period and duration);
• Light indication of device operating modes;
• Data exchange with a personal computer via RS-485 interface (ModBus RTU protocol);
• Generates "Error" signal;
• Software change of conversion characteristic parameters.

Production modifications:

• Housing for mounting on DIN rail;
• RS-485 interface (Modbus RTU);
• Power supply from AC mains rated 110..220V or DC source rated 12..24V;
• Device with one or two four-digit seven-segment indicators;
• Type of input sensor: TO, PT, AN, AT or UV (universal input);
• Types of output devices: R, OC, OK.
