Allen-Bradley 700-HAX2A1-4 General Purpose Relay

Configured for direct physical/electrical execution in Allen-Bradley control circuits and PLC switching loops, the Allen-Bradley 700-HAX2A1-4 (700-HAX2A1-4 General Purpose Relay) provides high-density signal switching and status isolation.

Hardware Specifications

Backplane Communication and Deterministic Bus Performance

Configured for interposing control loops linked to Allen-Bradley I/O systems, the 700-HAX2A1-4 executes high-velocity coil actuation without feedback jitter across deterministic EtherNet/IP process loops. Fast contact actuation times ensure predictable signal state transition execution, providing robust galvanic isolation between field actuary devices and PLC I/O channels without degrading firmware flash compatibility or backplane control timings.

Frequently Asked Questions

Q: Can the 700-HAX2A1-4 relay be plugged into or removed from its base socket while coil power is applied?

A: Live hot-swapping under load is strictly prohibited. Operating control voltage to the 120 VAC coil and field contacts must be completely de-energized before inserting or extracting the relay from its tube-style socket.

Q: How is visual contact status determined during operation?

A: The module includes a mechanical ON/OFF flag indicator alongside an integrated LED option that illuminates when 120 VAC power is present across the coil terminals.

Field Installation Guidelines

1. Ensure all 120 VAC coil control lines and 6 A contact circuit feeds are fully de-energized and locked out before installation.
2. Align the keyway on the 8-pin tube-style base with the center orientation notch of the matching DIN-rail socket.
3. Push the relay straight into the socket until the pin terminals seat fully into the receptacle contacts.
4. Verify physical pin engagement and secure any socket retention clips to maintain terminal stability under vibration.
5. Apply 120 VAC coil voltage to test mechanical flag trip actuation and observe status LED illumination under active load.
