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.

•16 differential; programmable by channel for specific thermocouple type or voltage.

Input Types:

•J, K, T, E, R, S, B, N; and ±10V, ±5V, ±1V, ±100mV

Input Connector:

•Subminiature-plug
