TWO WIRE OR FOUR WIRE 4-20MA TRANSMITTER PRINCIPALS

AC SSR USING CRYDOM RELAY. 110V INPUT AND 24V 50MA OPEN COLLECTOR OUTPUT

ROTARY INCRIMENTAL ENCODER

MICRO CONTROLLER WITH COM PORTS FOR INTERFACING

CONVENTIONAL AND HART TRANSMITTER PRINCIPALS

CRYDOM CROUZET MOSFET BASE DC SSR

Inductive Dc Solenoid load which generates back e.m.f while switching 'off ' action of solenoid. Freewheeling diode across and near to load is shortest path for this generated back E.M.F.  Fast de-magnetization with this diode.
