For thermocouples K, S, R, J, T, E, N, B.
• Comply with polarity
• For possible extensions, use compensated cable and terminals suitable for
the thermocouples used (compensated).
• When shielded cable is used, it should be grounded at one side only.
For thermoresistances PT100, Ni100.
• For the three-wire connection use wires with the same section.
• For the two-wire connection short-circuit terminals 16 and 18.
• When shielded cable is used, it should be grounded at one side only.

For thermoresistances NTC, PTC, PT500, PT1000 and linear potentiometers.
When shielded cable is used, it should be grounded at one side only to avoid
ground loop currents.
For linear signals in Volt and mA
• Comply with polarity
• When shielded cable is used, it should be grounded at one side only to
avoid ground loop currents.
• To power the sensor connected to AI2 through +V (terminal 15 or 25),
short-circuit 0 V (terminal 14 or 24) with AI2 ground input (terminal 17).
• + V at 12Vdc or 24Vdc can be selected by configuring parameter 282
(GROUP R - - Display and interface).

To enable CT input, modify parameter 287
• Input for 50 mA amperometric transformer.
• Sampling time 100 ms.
• Configurable by parameters.
Digital inputs can be enabled by parameters.
