| Number of inputs |
4 (8 with scanner option) |
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) |

Isolation |
Sensor inputs optically isolated from other circuits but not from each other |

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 rdgs/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 rdgs/s.
