Voltage Input Module, -10 VDC to +10 VDC or -5 VDC to +5 VDC,

32 Channels

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.
