Two-position three-channel regulator RD3

The device carries out two-position control of the input physical quantity through three channels according to the two-position law.

RD3 allows you to perform the following functions:

• measurement of the parameters of various objects using standard sensors (resistance thermocouples (temperature sensors) ТСМ (50М, 100М) and ТСП (50П, 100П, Pt100), thermocouples (ТХК, ТХА, ТЖК, etc.), sensors with a unified output current signal and voltage) across three channels;
• display on the built-in LED digital indicators of the current, set parameter values and the number of the corresponding channel;
• the ability to change the set value (setpoint);
• data exchange with a personal computer via RS-485 interface;
• psychrometric method for measuring humidity;
• regulation according to the three-position law on one of the channels;
• work in the mode of a pulse regulator;
• signal generation "Error";
• program change of parameters of the transformation characteristics.
