Two-position two-channel regulator RD2

The RD2 temperature meter / regulator carries out on-off regulation of the input physical quantity, automatically controls the state of the input sensor, the finding of the measured input quantity outside the set measurement range, the correctness of the parameter input and the calibration of the device. According to the results of the control, the signal “Error” is generated.
The regulator can be executed in two power modifications: AC voltage network 90..240V (IPI) or DC voltage source = 12..24V (IP24). It is also possible to manufacture models with two indicators for the simultaneous display of the current, setpoint and letter information.

Appointment of RD2

Regulator two-position two-channel RD2 is intended for measuring, indicating and regulating the temperature of various media in refrigeration equipment, drying chambers, industrial / household furnaces and other technological equipment, as well as for measuring and regulating other physical quantities (level, flow rate, pressure, humidity, etc.) etc.) using sensors with a unified analog signal.

General functions and operating modes of the RD2 temperature controller:

• measurement of temperature (or other physical quantities) of objects using resistance thermocouples (temperature sensors) ТСМ (50М, 100М) and ТСП (50П, 100П, Pt100, Pt500, Pt1000), thermocouples (ТХК, ТХА, ТЖК, etc.), sensors with unified output signal of current АТ (0..5 mA, 0..20 mA, 4..20 mA) and voltage АН (0..1 V, 0..5 V, 0..10 V);
• regulation of input physical quantities according to the two-position law in two channels;
• temperature control according to the three-position law (one channel);
• moisture measurement based on the psychrometric method;
• display of measured values on the built-in LED indicator (digital temperature indicator);
• scaling the measurement scale (for sensors АН and АТ);
• light indication of operating modes temperature regulator RD2 (sensor failure, programming);
• software change of parameters of transformation characteristics (slope, offset);
• digital filtering of measurements (filter depth - up to 10 measurement periods);
• changing the indication period of the measured value;
• digital calibration of the input channel;
• programming by buttons on the front panel of the device;
• password protection of parameters;
• saving settings when the power is turned off;
• built-in power supply = 24V, 100mA for active sensors in modifications with АН and / or АТ;
• RS-485 ModBus RTU interface.

The RD2 temperature regulator has a more advanced version - a universal device RP2-U... RP2-U is produced both for panel mounting and for installation on a DIN rail. The new modification completely replaces the functionality of the two-position single-channel temperature controller RD2, and also has a number of additional functions.

We recommend using a new universal device instead of the RD2 regulator RP2-U, which completely replaces RD2, has more functionality. RP2-U has been tested for EMC, statics, meets the IP54 standard from the front panel.
