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.
