Intrinsically Safe Power Supply Unit (EWS)
Intrinsically safe supply circuit 12 V to supply intrinsically safe KEM pickups and amplifiers installed in hazardous areas.
Two intrinsically safe signal input circuits EX II 2 G [EEx ia] IIC to connect pickups and amplifiers as per DIN 19234 (NAMUR) in two- or three-wire technique and active and passive pickups. LEDs will indicate short circuit and line breakage.
Specifications:
Outputs
- Open collector
- PLC output active 24 V
- NAMUR DIN 19234
The EWS is an intrinsically safe supply unit and separation amplifier. The EWS supplies KEM pickups and amplifiers installed in hazardous areas and transmits the output frequency of these pickups.
The EWS must be installed outside hazardous areas. All in- and output circuits are isolated.
