Electronic Valve Positioner

Marsh Automation Pvt Ltd offers an Electronic Valve Positioner. These units are used for controlling the mechanical position of final control elements with respect to incoming commands received from the controllers such as PID/DCS/QCS, etc., and also to give feed back signals. The incoming control command in the form of 4-20 mA/0-20 mA or 0-10 V DC/0-5 V DC is converted into 230 V AC 50 Hz or 110 V AC 50 Hz 1 phase outputs by the positioner to run the actuator motor in forward and reverse directions. The positioner while generating the output signal also takes into account the present position of the final control element, dead band, feedback signal, time delay, etc. The positioners are supplied in two different forms field mounted and panel mounted for single and three phase requirements. Technical specifications: power supply - 230 V AC 50 Hz, standard ±10%; 110 V AC 50 Hz, optional control signal (input) and retransmission signal (output).
