This device is designed to provide an electrical barrier
between control devices and hazardous location devices.
This is a non-fused device, a failure may cause it to fail in
a shorted state.
Must be installed in a suitable enclosure.
Return line must be referenced to 0V, the PLC input must
have a low resistance path the 0V. This is essential to the
proper operation of the barrier in over voltage situations.
If a low impedance to 0V cannot be guaranteed on
the return path, Wieland recommends the use of two
barriers (one per signal) and to connect one of the return
terminals on each barrier directly to ground
PLC input must have low
resistance to ground.
Wiring must be suitable for the
area. The input is not protected by
the barrier
