Remote Control with 4-20 mA Output Signal (Option)
Instead of 6 output signals for remote control, an analog output signal of 4-20 mA can be generated using contacts
28/29. The customer must provide a 24 VDC supply voltage with a loop resistance of max. 600 Ohms (see R). In
that case contacts 10 to 21 are no longer available. Contact 28 should be connected to the positive, 29 to the
negative signal of the supply voltage.
The analog signal can have only 7 different values:
4 mA no ice
4.5 mA 0-20 % ice
7.2 mA 20-40 % ice
10.4 mA 40-60 % ice
13.6 mA 60-80 % ice
16.8 mA 80-100 % ice
20 mA 100 % ice
There will be no intermediate mA output as measurement is based on a 6 step measurement only.
