15.8 COMPACT PLC AND RELAY EXPANSION CARD
The Compact PLC and the relay expansion card can be mounted either beside each other or piggyback
(one on top of the other).
1. Beside Each Other
If the two housings are mounted next to each other, please follow installation and mounting instructions
given.
2. Piggyback
With this type of installation, the relay expansion card is first mounted either directly on the back panel
of the enclosure or on the mounting rail (see instructions). Then the Compact PLC is fastened to the
relay expansion card with the two mounting plates.
The mounting plates are included with the delivery of the relay expansion card.
