8-channel Field Terminals
SafetyNet IO Modules use standard MOST
8-channel Field Terminals. Depending on
the application, the Field Terminals may be
for general purpose, non-arcing or nonincendive field wiring, may incorporate
fused disconnects and may be for 2-, 3- or
4-wire transmitters.
Fused disconnect
The fused disconnect Field Terminals
incorporate a 2A fuse that can be partially
withdrawn from the Field Terminal to act as
a loop disconnect.
Tag strip
Each Field Terminal is supplied with an
integral tag strip, which is hinged to provide
access to the wiring terminals and the fuse
disconnects.
Field Terminal clicks
on to Carrier
The Field Terminal is easily removed from
the Carrier – it is held in place by a sprung
latch that can be released without the need
for tools. This simplifies connection of the
field wiring. The Field Terminal is secured in
place by the insertion of the IO Module.
Wiring to Field Terminals
SafetyNet IO Modules all use 8-channel
Field Terminals, to which wiring with a cross
section of up to 2.5mm2 can be connected.
Each termination point is clearly numbered
to simplify recognition of each terminal. The
two rows of terminals are offset to allow
access to the lower row when wiring is in
place.
