Description
The SNAP-AIV-32 and SNAP-AIV-32-FM modules can be
configured for either -10 VDC to +10 VDC or -5 VDC to +5 VDC
operation on each of its 32 channels. See the table on page 3
for I/O processor compatibility. The SNAP-AIV-32-FM is Factory
Mutual approved.
Note that all channels share a common reference terminal.
(For channel-to-channel isolated modules, see Opto22 form
#1182.)
SNAP TEX cables and a breakout rack are available separately
for wiring points to field devices (see form #1756, the SNAP TEX
Cables & Breakout Boards Data Sheet). The SNAP-HD-BF6 wiring
harness connects the module to the breakout rack, which can
then be wired to field devices. The SNAP-HD-CFB6 wiring
harness has flying leads to connect to field devices.
See the dimensional drawing for the module on page 39.
