Specification for SiteI/O 10/0
DESCRIPTION: The SiteI/O 10/0 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 ten analog, digital, and/or dry contact type signals. Individual hardware
jumpers set signal-type selections. Screw terminal blocks are provided to terminate power,
communication, and input signal wiring.
