Three-channel two-position regulator RD3 measures, controls, and regulates temperature or other physical quantities using standard sensors on three channels, with output devices connected via relay, triac optopair, or open collector scheme.
Three-channel two-position regulator RD3 performs two-position regulation of the input physical quantity on three channels according to a two-position law.
RD3 enables the following functions:
- measurement of parameters of various objects using standard sensors (resistance temperature detectors (temperature sensors) TSM (50M, 100M) and TSP (50P, 100P, Pt100), thermocouples (TXK, TXA, TJK, etc.), sensors with standardized current and voltage output signals) on three channels;
- display on built-in LED digital indicators of current and setpoint parameter values and channel number;
- ability to change the setpoint value;
- data exchange with a personal computer via RS-485 interface;
- psychrometric method for humidity measurement;
- three-position regulation law on one of the channels;
- operation in pulse regulator mode;
- generation of "Error" signal;
- software adjustment of the conversion characteristic parameters.

What types of sensors does the three-channel two-position regulator RD3 support?
The RD3 device supports connection of resistance temperature detectors (TSM 50M, 100M, TSP 50P, 100P, Pt100), thermocouples types TXK, TXA, TJK, as well as sensors with standardized current and voltage output signals.
What power supply options are available for the RD3 device?
The RD3 regulator can be powered from an AC mains voltage of 140..220 V or from a DC source of 12..24 V, depending on the device modification.
How does regulation work in the RD3 device and what types of output signals are supported?
RD3 provides two-position regulation on three channels according to the two-position law; three-position regulation is possible on one channel. Output signals can be delivered via relays, open collector, or optotriac.
Can RD3 be connected to a PC for setup and monitoring?
Yes, the device is equipped with an RS-485 interface (ModBus RTU) for data exchange with a personal computer for configuration and parameter monitoring.
How are readings and information displayed on the RD3 regulator?
Current and setpoint parameter values, as well as the active channel number, are displayed on built-in LED digital indicators. The number of indicators depends on the device modification.
