Two-position eight-channel regulator RD8

The two-position eight-channel regulator RD8 carries out two-position regulation of the input physical quantity in eight channels according to the two-position law. The device operates in a set with an output expander BR8 (input sensors are connected to the regulator and it controls the output expander via RS-485, to which the executive devices are connected.

RD8 allows you to perform the following functions:

• measurement of 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) on eight channels;
• display on the built-in LED digital indicators of the current, set parameter values and the number of the corresponding channel;
• light indication of the device operating mode;
• 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 multi-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.

Manufacturing modifications:

• panel version (model with three indicators);
• power supply from an alternating voltage network with a nominal value of 140..220V and from a direct voltage source with a nominal value of 12..24V;
• types of input signals TS, PT, AN and AT;
• RS-485 interface (ModBus RTU);
• types of output signals: P, OK, OS.
