Figure B-1 Definition of Output Function of XK3190-C602 Relay Box
During installation, connect the cable coupled with relay J1 terminal to output terminal block
of C602 instrument, i.e. change output signal of C602 instrument transistor to output signal of
relay.
The relay is connected with AC powered inductive load, such as AC contactor coil,
electromagnetic valve etc., and parallel connected with RC absorption loop on output terminal or
load so as to reduce interference, and prolong service life of relay contactor. Thin-film capacitor
can be used for the capacitor, electric capacity is about 0.5 time of load current (Ampere), with
unit 2F, voltage resistance should be more than 3 times of effective value of power supply voltage;
resistance value is about 2 times of power supply voltage (V), with unit 4; the power can be
selected with more than two times of calculated power. When the relay is connected with DC
powered inductive load, free wheel diode should be parallel connected to the load.
