Macromatic ARP012A5R, 8 Pin Plug-In Alternating Relay, 12V AC/DC, 10A DPDT Cross Wired
Macromatic ARP Series plug-in alternating relay, 8 pin base, 12V AC/DC control voltage, 10A DPDT Cross Wired output, for use with a 8 pin 70169-D octal socket.
Why Choose the Macromatic ARP012A5R Alternating Relay?
The Macromatic ARP012A5R is an 8 pin ARP Series alternating relay with 12V AC/DC control voltage and a 10A DPDT Cross Wired output. It is built for duplex control circuits where two loads need to alternate so run time stays balanced across both loads.
A control switch starts the alternating action, and the relay contacts change state when the initiating switch opens. The ARP012A5R plugs into an 8 pin 70169-D octal socket, keeping replacement and panel service straightforward. The cross wired DPDT output supports added load capacity when the application requires it. Two LED indicators show which load energizes first.
🔁 Alternates Two Loads
Balances run time between two connected loads in duplex control applications
⚡ Relay Output
10A DPDT Cross Wired output for the connected load control circuit
🔌 Plug-In Socket Design
8 Pin relay designed for a 8 pin 70169-D octal socket
💡 LED Load Indication

📋 How the Alternating Relay Works
The ARP012A5R is used where two loads need to share run time instead of one load doing most of the work.
Start Signal: A control switch starts the alternating action.
Relay Changeover: The output contacts change state when the initiating switch opens.
Load Alternation: The connected loads alternate on each cycle to help balance usage.
Selector Function: The unit also has a low profile selector switch to lock into one load, so the same load runs first.

📋 Basic Installation Overview
1. Confirm Relay Type: Verify the Alternating Relay function, 12V AC/DC, and 10A DPDT Cross Wired rating match the panel requirements.
2. Match the Socket: Install the relay with the proper 8 pin 70169-D octal socket and confirm terminal wiring before energizing the circuit.
3. Wire the Control Switch: Connect the initiating switch so the relay can change state when the switch opens.
4. Connect the Loads: Wire the two loads according to the relay diagram and confirm the contact rating is not exceeded.
5. Test Alternation: Cycle the control switch and verify the load indication and alternating sequence before putting the equipment into service.
Always follow the Macromatic ARP Series installation manual and applicable electrical codes before operation.
