3.2.1
PCD7.LRL2-P5, -.LRL4-P5 and -.LRS4-P5 (230 VAC models)
Power supply
Terminals 1 + 2
230 VAC +10%/-15%, 50/60 Hz
Max. power consumption (unloaded)
8 W
Max. power consumption (loaded)
18 W
The controller is “unloaded” when no external load is applied. Therefore, the only
load placed on the controller is the inherent load (8 W) of the electronics them-
selves. The heat dissipation amounts to 8 W.
The controller is “loaded” when, in addition to the inherent load, an extra total load
of max. 300 mA is applied at the 24 VAC output terminals. The max. no-load out-
put voltage at terminals 3 and 4 is 33 VAC (typically:29.5 VAC).

PCD7.LRL5-P5 and PCD7.LRS5-P5 (24 VAC)
Power supply
Terminals 3 + 4
24 VAC ±20%, 50/60 Hz
Max. power consumption (unloaded)
7.2 W
Max. power consumption (loaded)
21.6 W
The controller is “unloaded” when no external load is applied.
The heat dissipation amounts to 7 W.
The controller is “loaded” when an additional total load of max.
600
mA
is applied
at the 24 VAC output terminals.
