Overview
The Macromatic ARF120A6R is an 8 pin alternating relay designed to equalize run time between two loads, such as pumps, compressors, or motors. It features a 120V AC/DC control voltage, 10A SPDT output, and a flange enclosure for convenient inner door mounting.Alternating Relay10A SPDT8 Pin
The relay changes output state when the initiating control switch opens, allowing connected loads to alternate operation and reduce uneven wear.
🔁 Balanced Load Operation
Alternates Two Loads: Helps equalize operating time between paired equipment.
Selector Switch: Allows operation to alternate between loads or lock into one selected load.
LED Indicators: Two LEDs display relay and load status for quick troubleshooting.
Key Features
- 120V AC/DC control voltage: works with common control circuits
- 10A SPDT output: supports control of industrial loads
- 8 pin design: includes back mounted socket
- Flange enclosure: mounts to inner door for easier access
- Low profile selector switch: alternate loads or lock into one load
- Long mechanical life: rated for 10,000,000 operations
- Pilot duty rated: B300 and R300 N.O. pilot duty
- UL, CUL, and CE approvals: industrial control compliance
✅ Why Choose This Alternating Relay?
This relay is ideal when two loads need to share run time evenly, helping reduce overuse of one load and extending equipment service life.
Applications
- Duplex pump control panels
- Lead/lag motor control
- Compressor sequencing
- Fan and blower alternation
- Industrial control cabinets
- Equipment runtime balancing
Operation Notes
- Control switch closes to initiate load operation
- Selected load energizes through the relay output
- Control switch opens after operation is complete
- Relay changes state for the next cycle
- Next demand energizes the alternate load unless selector switch is locked to one load
⚠️ Important Product Note
Image is for reference only; actual part may differ.
Use the proper included 8-pin back mounted socket for listed installation.
Verify connected load ratings do not exceed relay contact specifications.
Performance Benefits
- Equalizes run time between two loads
- Helps reduce premature wear on favored equipment
- Allows manual load selection when needed
- Provides quick visual status with two LED indicators
- Inner door mounting improves service access
