SNAP-AIV (Two channels)

Four-channel module wiring is shown on page 28.

IMPORTANT: The mounting rack connector has 24 pins;

the module connector has 20 pins. The extra pins on the

mounting rack connector prevent misalignment of the

module during installation.

Description

The SNAP-AIV and SNAP-AIV-4 modules can be

configured for either -10 VDC to +10 VDC or -5 VDC to +5

VDC operation on each channel. The SNAP-AIV provides

two channels, and the SNAP-AIV-4 four. If you need a

module with more channels, see page 29. See the table

on page 3 for I/O processor compatibility.

Note that all channels share a common reference

terminal. If you need two isolated channels on the same

module, see Opto22 form #1182.
