Csn14/Lv/ (T, B, & S) Low Voltage Cards - Omega Engineering OMB-NETSCAN 1500 User Manual

CSN14/LV/ (T, B, & S)
There are three versions of low voltage signal conditioning cards for use with NetScan. Each card supports 16
differential input channels and is capable of measuring analog input signals on any of four programmable ranges:
±100 mV, ±1 volt, ±5 volt and ±10 volt. The cards share the same signal conditioning characteristics, but differ in
their style of input connector, i.e., terminal strip, BNC, and safety jack (CSN14/LV/T, CSN14/LV/B and
CSN14/LV/S, respectively).
Number of Inputs: 16 differential; programmable by channel for input range
Input Types: ±10V, ±5V, ±1V, and ±100mV
Input Connectors: Removable screw terminal blocks, BNC, or Safety Jacks
