Overview
The Techmor AC-1-4 is a precision four channel module that converts 0-5 volt analog
inputs to digital messages that can be received via CAN bus. The AC-1-4 has an
integrated 5 volt, 150 mA supply to power sensors or other peripherals. The CAN ID of
the unit can be changed via a CAN bus message.
Connections
All connections to the AC-1-4 are through the two multi-conductor cables on either end of
the enclosure.
Input
The AC-1-4 has four 16-bit 0-5 volt analog channels. The inputs are accessed via the 6-
conductor cable on the
“Input” side of the enclosure. The channels are single-ended and
share a common ground.
