Allen-Bradley 700-HAX2A1-4 General Purpose Tube Base Relay
The Allen-Bradley 700-HAX2A1-4, also cataloged as the 700-HAX2A1-4 General Purpose Relay, operates as a dedicated hardware component for physical signal execution and power switching within control panels and automated switching circuits. The 2-pole relay incorporates a 120 VAC (50/60 Hz) operating coil driving contact outputs rated for up to 6 A continuous switching current. Integrated tube-base pin-style terminals ensure mechanical alignment into socket assemblies, while an onboard visual LED indicator displays active coil energization status.

Backplane Bus Communication & Deterministic Networking
The 700-HAX2A1-4 provides electrical isolation between low-voltage digital PLC outputs and higher-voltage AC field actuator loads. Contact assemblies resist oxidation and switching transients during inductive load operation, maintaining reliable circuit continuity across control loops. Precise coil pull-in and drop-out times preserve deterministic output execution without compromising firmware flash compatibility across connected controller backplane circuits, while integrated LED illumination provides instant visual confirmation of coil power states during panel testing.
Frequently Asked Questions
Q: What operating voltage and frequency are required to actuate the 700-HAX2A1-4 relay coil?
A: The relay coil requires a nominal control voltage of 120 VAC at 50/60 Hz.
Q: What mounting format and pin configuration does the 700-HAX2A1-4 utilize?
A: The module uses a tube base enclosure with pin-style terminals designed for insertion into matching panel-mounted relay sockets.
Q: How is active coil energization visually verified on the hardware?
A: An integrated LED status indicator on the relay housing illuminates when 120 VAC is applied across the coil terminals.
Field Installation Guidelines
- Isolate all control circuit power sources before inserting or removing the relay from its socket.
- Align the tube-base keyway and pin terminals of the 700-HAX2A1-4 with the matching socket receptacle.
- Insert the relay firmly into the socket until seated, engaging retaining clips where installed.
- Terminate field wiring onto socket screw terminals, verifying that continuous circuit current does not exceed 6 A per pole.
- Apply 120 VAC coil control power and check the status LED to confirm active switching state.
