The CSN14/HV/S card contains 16 differential input channels and is for use with “safety jack” type connectors. Each
CSN14/HV/S card is capable of measuring analog input signals on any of the following three programmable ranges:
±2.5 volt, ±25 volt and ±250 volt.

Number of Inputs:
16 differential; programmable by channel for input range
