NB!

Please note the values available within the different standard groups of resistors:
E12: Closest standard value is 470

, creating an input of 449.9

 and 8.997V.

E24: Closest standard value is 510

, creating an input of 486.4

 and 9.728V.

E48: Closest standard value is 511

, creating an input of 487.3

 and 9.746V.

E96: Closest standard value is 523

, creating an input of 498.2

 and 9.964V.

When used for voltage, analog inputs are scalable by parameters for each input.

When used for temperature sensor, analog inputs scaling is preset to necessary signal level for specified temperature span.

When analog inputs are used for temperature sensors, it is possible to read out feedback value in both 

°

C and 

°

F.

When operating with temperature sensors, maximum cable length to connect sensors is 80 m non-screened / non-twisted wires.

Analog outputs are scalable by parameters for each output.

The function assigned is selectable via a parameter and have same options as for analog outputs on control card.
