Fig. 3-24: Contactor relays: voltage ranges
Auxiliary contact blocks Auxiliary contact blocks can be built on as follows:
Frame size S00: none
Frame size S0: a maximum of two 1-pole auxiliary contact blocks
Power consumption Variant 1: The power input of the magnet coils for contactor relays in frame
size S00 is 2.3 W at 24 VDC (operating range: 0.7 to 1.25 x U
S
).
Variant 2: Contactor relays with reduced coil performance in frame size
S00, P = 1.4 W at 24 VDC (operating range: 0.85 to 1.85 U
S
).
The power input of magnet coils for contactor relays in frame size S0 is
4.2 W at 24 VDC (operating range: 0.7 to 1.25 x U
S
).
