Regulatory instruments R-25 are designed for use in systems of automatic regulation and control of technological processes.
The devices perform the following functions:
The summation of signals from transducers with natural electrical output signals.
The introduction of information about the specified value.
The formation and amplification of the error signal.
The formation of the output electrical pulses of constant or AC to control the actuator with a constant the speed of movement.
The formation, together with the Executive mechanism constant speed proportional-integral control law.
The formation, together with differentiator and Executive the constant speed mechanism proportional-integral-differential control law.
The manual control of the actuating mechanism.
The conversion of the signal from the differential transformer measuring mechanism in the DC signal.
Technical parameters of the device:
The power of the devices is performed on a single-phase network
AC voltage 220V, frequency 50±1 Hz.
The powerconsumed from the network, no more than 22 In A. 2.3. Input impedance: (a) for signal 0-5 mA - 100 Ohms;b) for signal 0-20 mA - no more than 25 Ω;C) for 0-10V signal is not more than 15 com.
Output signals:
a)the voltage pulses of constant pulsating DC average voltage 24 V;
b) changing the state of the contactless keys that allow switching pulsed DC or AC.
Output contactless electronic key devices commute AC frequency of 50 Hz and a pulsating direct current with an amplitude value to 1 And when the current value of the current from ML to 0.5 and the current value voltage external power supply output circuits of not more than 250 C.
View and load resistance for the output signal 24 VDC, plug-in to the internal source - active-inductive with the active resistance is not less than 100 Ohms.
The pointer movement position of the actuator when the change of signal transducer position 1B, not less than 100% of the scale indicator.
The range of the dead zone And a percentage of the nominal range of input signal change for devices of versions 1.2 and 0.4 nominal range input devices modification 3 is 0.5+0.3 to 5±2.
Weight of the device is not more than 5 kg
