Data
Supply voltage
24 V a.c. +/-20% 50/60 Hz or 24 V d.c. +/-20%
(the supply voltage is galvanically separated from the input and output signals.
Input/output are not individual galvanic isolated)
Power consumption
Controller
20 W coil for AKV or AKVA
15 VA / 10W
55 VA
Input signal
* Ri =
0(4)-20mA: 33 ohm
0(2)-10 V: 100 kohm
Level signal *
4-20 mA or 0-10 V
ICM valve feedback signal *
From ICAD 0/4-20 mA
Contact function start/stop of regulation
Relay output
