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-AIMV2-4 module provides four channels of
analog to digital conversion. See the table on page 3 for I/O
processor compatibility.
Each channel on the module can be configured for -50 mV
DC to +50 mV DC or -25 mV DC to +25 mV DC.
Note that all inputs share the same reference terminal.
