Use as a limit switch for controlling motor actuators, valves, pumps, thermal aggregates, among other things; function: Comparison of an analog input variable (0-10VDC) with a setpoint range; if the temperature exceeds or falls below this range is set via the corresponding output, an actuator is activated, which compensates for the control deviation; among other things, the MST 101 voltage control of an engine-driven variable transformer; in connection with a corresponding measuring converter (0-10V) can also other parameters can be adjusted.; via its digital outputs the controller can be integrated into a PLC control or to the optional step motor control MST 102.This text is machine translated.
