12V AC/DC Control
Macromatic ARP012A3R: 12V AC/DC 10A DPDT Cross-Wired Plug-In Alternating Relay
Balances operating time between two loads using an 8-pin plug-in design and 10A DPDT Cross-Wired output.
✓ Equalize Runtime Between Two Loads
Control: 12V AC/DC | Output: 10A DPDT Cross-Wired
Overview
The
ARP012A3R is a Macromatic alternating relay designed to equalize run time between two loads. It operates from 12V AC/DC control power and provides a 10A DPDT Cross-Wired output. The cross-wired contact arrangement supports applications where added load capacity is required.12V AC/DC10A DPDT Cross-Wired8-Pin
The plug-in housing is designed for use with a
8-Pin 70169-D Octal Socket. A control switch initiates the alternating sequence, and the output contacts change state when the initiating switch opens.
⚙️ Dual-Load Alternating Control
Runtime Balancing: Alternates operation to distribute use across two loads.
Status Indication: Two LEDs identify relay/load status and help confirm which load is selected in the sequence.
Manual Selection: A low-profile selector switch can lock operation to one load or control which load runs first.
Key Features
- 12V AC/DC control voltage: matches the specified control circuit
- 10A DPDT Cross-Wired output: switches connected load-control circuits
- 8-pin connection: supports organized panel wiring
- Cross-wired contacts: provides added load capacity for dual-load applications
- Plug-In Socket Mount: fits the specified control-panel installation method
- 8-Pin 70169-D Octal Socket: compatible connection platform
- 10,000,000-operation mechanical life: designed for long service
- Industrial approvals: C UR US, CE, CSA, C UL US Listed (with Socket)
✅ Why Choose This Alternating Relay?
The ARP012A3R automatically rotates operation between two loads to help maintain balanced run time. Its 10A DPDT Cross-Wired output, LED indication, and plug-in construction support dependable dual-load control-panel operation.
Applications
The ARP012A3R is intended for two-load control applications where alternating operation and balanced usage are required:
- Dual-load control systems that require automatic alternation
- Installations where balanced run time prevents one load from being consistently favored
- Control panels using an 8-pin plug-in relay connection
- Two-load applications requiring added output contact capacity
- Systems that need a manual lead-load or single-load selection option
Operation Notes
- A control switch initiates the alternating action.
- The output contacts change state when the initiating switch opens, causing the loads to alternate.
- Use the two LED indicators to verify relay/load sequence status.
- Use the low-profile selector switch when one load must be locked on or designated to run first.
⚠️ Important Product Information
Image is for reference; actual part may differ.
Verify the control voltage, output configuration, and socket or mounting requirements before installation.
Follow the Macromatic installation manual for wiring and setup.
