Module
Configurations
The 1260-132 is a 1 x 23, two wire,high voltage reed switch
multiplexer module The 1260-132 uses an isolation relay to
disconnect the 1x23 multiplexer when cascading multiple 1260-132
modules to build larger multiplexers . This additional relay reduces
the capacitance and increases the insulation resistance for large
multiplexer configurations
Front Panel
