Wiring Connections and Cabling
The IMASI23 module has three card edge connectors to supply
power (P1), connect I/O expander bus communication (P2),
and provide analog inputs (P3).
Wiring
Install the analog input module in the module mounting unit
to connect the module to the +5 VDC voltages needed to power
the circuits. The module mounting unit also connects P2 to the
I/O expander bus for communication with the controller. P1
and P2 connection require no additional wiring or cabling.

NOTE: A dipshunt on the backplane of the module mounting unit connects the
I/O expander bus between the ASI module and the controller. Locate the mod-
ule so the bus can connect to them or they will not communicate.
