Green - Normal Operation
Amber - Fault Condition
Amber light typically indicates a ground
fault on the output.
At 45 VDC the fault light will illuminate
(even with no output connected)
If the temperature rises above 75oC a
thermal fuse will open the output.

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

Wiring must be suitable for the

PLC input must have low

This module provides isolation for a
circuit on the load side of the module
to be rated as non-incendive, and
is to be used on digital inputs or
outputs. The DNIB allows the use
of non-rated wiring to end devices
in Class 1, Zone 2 / Division 2 areas,
subject to the allowances of the
Canadian Electrical Code.
