10 Bulletin 1405 (M620) Operating Instructions

Analog outputs selected as ‘I’, ‘=’, ‘P’ or ‘S’ provide a linear
measurement scaled from zero to the full-scale value as configured by
the V

nominal

and I

nominal

settings.

Refer to Table 4 and Table 5 for more information.

With the output range set to 0 to 20 mA, the relationships are:
