CONTROL RELAY WITH AN INTRINSICALLY SAFE ENTRY PS-42
CERTIFICATE: FTZU 10 ATEX 0039
FEATURE OF APPROVAL: Ex I (M1) [Ex ia Ma] I
Control relay type PS-42 with an intrinsically safe entry is designed to remotely-controlled operating of devices with protection against unauthorized switching in the event of a short circuit in the control circuit. The control input of the relay is intrinsically safe explosion-proof [Ex ib]. The relay is designed for mounting on splint TS35. On the front panel there are lights indicating different operating states of the relay, the blue light indicates relay output. Through an opening in the front plate you can set the threshold contact resistances relay off. The resistance is factory set 550Ω.
