WF 3132 C-Series, Multiplexer Module

The WF 3132 from WireFlow is a 32-channel Multiplexer/Matrix Switch for Compact RIO and Compact DAQ. 
It is a general purpose switch that can be used to switch almost any type of signals.
The relays have ruthenium sputtered contacts making them ideal for low current switching, but are at the same time capable of switching up to 0.5A. 

The 32 SPST reed relays can be used in multiple configurations:


                         1 x 32 (1 wire)
                         1 x 16 (2 wire)
                                  1 x 8 (4 wire)
                                  Four  banks of 1 x 8 (1 wire)
                                  4  x 8 Matrix (1 wire)
