Configured for interposing signal switching and circuit isolation in control panels, the Allen-Bradley 700-HAX2Z24-4 (700-HAX2Z24) General Purpose Relay provides direct physical/electrical execution. The module utilizes a 24 VDC control coil to drive a 2-pole contact configuration rated at 6 A, featuring an 8-pin tube base pin-style terminal array and an integrated LED status indicator.

I/O Density Scaling & Deterministic Execution
The 700-HAX2Z24-4 interposing relay integrates into high-density panel layouts to support I/O density scaling and deterministic switching execution within Allen-Bradley Logix architectures. The 24 VDC coil circuit provides fast electromechanical response times, allowing PLC digital output cards to switch higher-voltage field loads or isolate sensitive logic circuits. High-dielectric isolation between coil and contact sets prevents transient voltage spikes from propagating back into controller backplane communication lines.
Frequently Asked Questions
Q: Can the 700-HAX2Z24-4 relay be plugged into a standard 8-pin octal socket without shutting off cabinet power?
A: Control power to the socket base must be de-energized prior to inserting or removing the relay. Hot-plugging under electrical load can cause arcing on the tube base pins, damaging socket contact springs.
Q: Is the integrated LED status light polarity-sensitive on the 24 VDC coil inputs?
A: Yes, DC coil models with LED indicators require correct polarity orientation on terminal connections A1 (+) and A2 (-) for the LED to illuminate when energized.
Field Installation Guidelines
Align the central keyway pin of the 8-pin tube base with the notch on a compatible Bulletin 700 octal relay socket.
Press the relay firmly into the socket base until the retention spring clip snaps over the top housing.
Wire field output loads and 24 VDC coil control leads to screw terminals using stranded copper conductors rated for 75 deg C.
Ensure load currents across the 2-pole contacts remain strictly within the 6 A continuous rating to prevent contact tip degradation.
Ground the socket DIN rail assembly to the main panel earth ground bus bar using a low-impedance conductor.
