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.
Number of Channels:
• 16 diff erential; 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
