Connection log Model 7707
Analog inputs
The following Model 7707 channels are used to measure analog input:
• Channels 1 through 10 are system measurement channels.
• Channel 15 is the 2-pole/4-pole selection relay.
• Channels 16 and 17 are the backplane isolation relays for sense and input respectively.
Operation
Operation to measure analog input is the same as operation for the Model 7700. The only exceptions are that the Model 7707
does not have any amps channels, and it does not have a cold junction for thermocouple temperature measurements.
Operation information for the Model 7700 switching module is provided in the Model 27xx User’s Manual. Section 2 covers
basic open/close operation, while the “Scanning” section covers scanning.
