Technical Description

Connecting Contactors

Use spark suppression for larger contactors and also interface relays to maintain the service life of the
UMC100 internal relays. For interfacing contactors with peak current > 0.5 A (Types A50 and larger) use
an interface relay as shown below.

1)
The contactor B6S-30-10-2.8 (24 V DC) is recommended as interface contactor due to its internal spark
suppression.
2)
All values only for contactors with spark suppression, see appropriate column.
Use interface contactor if longer service life is required.
3) Interface contactor is recommended (e.g. B6S-30-10-2.8).
4)
The contactors for higher currents are available with electronic interface only
5) Also available with electronic interface (AF50 to AF185).
