Extension module
BN 3081

Product Description

If more safety cicuits have to be switched, than a safety module provides,
the extension module BN 3081 is used. It offers safe and reliable contact
multiplication and re-enforcment for safety modules with monitoring of the
feedback circuit. Safe semiconductor outputs can be extended by relay
output contacts. The extension module has forcibly guided contacts and
can be delivered with different contact arrangements.
