Overview
The
Macromatic ARF012A3R is an 8 pin inner door mounted alternating relay designed for applications where the run time of two loads needs to be equalized. It features a 12V AC/DC control voltage and a 10A DPDT cross wired output for reliable load alternation.12V AC/DC10A DPDT8 Pin
This relay includes a flange enclosure for inner door mounting, allowing the relay to be accessed without opening the control panel door. It also comes with an 8 pin back mounted socket.
💡 Alternating Load Control
Equalized Runtime: Alternates two loads to help balance operating time between equipment.
Added Load Capacity: Used when additional load capacity is needed in two-load control applications.
Inner Door Access: Flange enclosure allows the relay to be mounted where it can be reached without opening the panel door.
Key Features
- DPDT cross wired output: designed for two-load alternating control
- 12V AC/DC control voltage: supports low-voltage control circuits
- 10A output contacts: rated for 240V AC / 30V DC switching
- 8 pin configuration: supplied with an 8 pin back mounted socket
- Two LED indicators: shows relay status at a glance
- Low profile selector switch: locks into one load or switches between two loads
- Control switch operation: initiating switch starts the alternating action
- UL, CUL, and CE approvals: built for industrial control applications
✅ Why Choose This Alternating Relay?
The ARF012A3R helps prevent one load from being used more often than the other. The selector switch can lock the same load to run first or allow switching between two loads to balance usage.
Applications
The Macromatic ARF012A3R is ideal for two-load control applications where balanced operation and added capacity are required:
- Pump control panels
- Compressor sequencing
- Motor load alternation
- Backup load operation
- Industrial control systems
Operation Notes
- Control switch initiates the alternating action
- Output contacts change state when the initiating switch opens
- Loads alternate to help equalize equipment run time
- Selector switch can lock the relay into one load when needed
- LED indicators show relay operating status
