RMOB-JR Relay Base Specifications 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. Phoenix Contact Inc. • P.O.
