Description
The RMOB-JR series of relay bases from Phoenix
Contact allows for a variety of pluggable octal style
relays to be used in a single DIN-rail mountable base.
The 8 pin style octal base will accept up to a 2 PDT
contact relay. The 11 pin style octal base will accept
up to a 3 PDT contact relay.
The RMOB-JR universal relay base can be used with
any coil voltage. For reduction of inventory costs coil
status indication bases are available for both 24 V dc
and 120 V ac relays, eliminating the need to purchase
relays with indicators.
The DIN-rail mounted design provides another benefit;
the separation of coil and contact wiring. This will
eliminate the likelihood of faulty triggering from
interference between the coil and contact wiring.
