Industrial alternating relay

The Macromatic ARP120A6R is an 8-pin plug-in relay designed for alternating two loads in industrial control panels. It operates on a 120V AC coil and provides a single SPDT contact set rated at 10 A for both 240V AC and 24V DC switching. A built-in LED indicates which load is next to energise.

Sustained load behaviour

The relay draws less than 3 VA burden and consumes 3 VA during continuous operation, keeping coil heating low inside enclosed cabinets. Its alternating mode energises load one and load two in sequence each time the control signal cycles, preventing one device from accumulating excessive run time. The transparent housing allows visual confirmation of the LED status without removing the cover.

Decisive specification

The 8-pin octal base and 120V AC coil voltage determine whether this relay fits an existing socket and control circuit. Builders using a different pin count, coil voltage or contact arrangement will need a different part. The selector switch for alternating mode is fixed on the unit and cannot be reprogrammed for single-load duty.

Questions about this item

How much heat and power does the 120 V AC coil draw when the relay runs continuously?

The coil consumes less than 3 VA, which equals 3 watts of heat, so it stays cool during all-day operation.

What socket or base must I already have to plug in this 8-pin octal relay?

You need a standard 8-pin octal socket wired for 120 V AC coil voltage.

Will the 10 A contacts switch the same 240 V AC or 24 V DC loads that my existing contactors handle?

Yes — the SPDT contacts are rated 10 A at 240 V AC and 10 A at 24 V DC, matching those older loads.
