CSN14/TC/P Thermocouple and Low Volts Card with Subminiature Plugs

The CSN14/TC/P card contains 16 differential input channels, each of which may be configured as any

thermocouple type or as a milli-volt input. Temperature values may be returned in units of °C, °F, °K, °R, or mV.

This signal conditioning card contains subminiature plug type connectors. There are no user configuration switches

or jumpers on the CSN14/TC/P card.
