Specification for SiteI/O 16/16
DESCRIPTION: The SiteI/O 16/16 is part of the SiteI/O-Line, which allows a complete SiteScan
monitoring/control system to be built a piece at a time. It is a 32 bit microprocessor-based device
designed to monitor up to sixteen analog, digital, and/or dry contact type signals, and control up to sixteen
digital outputs. Digital outputs are controlled through custom programming that is defined by the user.
The digital outout also have manual control or override capabilities through switched located on the
module. Individual hardware jumpers set input signal-type selections. Screw terminal blocks are
provided to terminate power, communication, and input signal wiring.
