Input configuration

Inputs can be configured from the front panel to accept any of the supported input types. Thermocouple and capacitance inputs require an optional input card that can be installed in the field.

Supported option cards

Thermocouple (3060), capacitance (3061), or scanner (3062)

Maximum update rate

10 rdg/s on each input, 5 rdg/s when configured as 100 kΩ NTC RTD with reversal on, 2 rdg/s on each scanned input (scanner option only)

Maximum update rate (scanner)

The maximum update rate for a scanned input is 10 rdg/s distributed among the enabled channels. Any channel configured as 100 kΩ RTD with reversal on changes the update rate for the channel to 5 rdg/s.
