ControlWave ExpressPAC is approved by UL as an
instrument. This certication does not allow instal-
lation of any other hardware, not indicated by the
model number, in the instrument enclosure. Wiring
to and from the I/O, communication and power con-
nections inside the enclosure, per the ControlWave
ExpressPAC manual, are, of course, allowed.

ControlWave ExpressPAC Process I/O
ControlWave Express I/O module is designed to
maximize usability while minimizing installation and
maintenance.
The I/O module provides a mix of analog and digital
inputs and outputs that are a perfect t for small
RTU applications.
