Specification for SiteI/O 32/0

 

 

 

 

 
DESCRIPTION:  

The SiteI/O 32/0 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 thirty-two 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.
