Table 1. Signal Descriptions
Signal |
Description |
TC<0..31>+ , TC<0..31>– - |
Thermocouple input channels—TC+ is the positive thermocouple input terminal, and TC– is the negative thermocouple input terminal. |
CJC<0..7>+, CJC<0..7>– |
Cold-Junction Compensation Channels—These terminals are used to measure the CJC thermistors on the terminal block. The CJC channels are sampled during a thermocouple acquisition for the associated thermocouple channel in order to compensate for the thermocouple cold junction. |
COM |
These terminals are connected to the isolated ground reference for all of the thermocouple channels. |
RSVD |
These pins are reserved for communication with the accessory. |
