700-HK32A2-4L | Allen-Bradley | 700-HK Series Slim Line DPDT Plug-In Relay

Product Overview

The Allen-Bradley 700-HK32A2-4L operates as a high-density interposing logic control relay within the 700-HK Slim Line product family. This compact, open-style switching component interfaces directly between low-power controller outputs and heavy field actuators, deploying a Double Pole Double Throw (DPDT) contact arrangement to isolate and switch independent electrical paths.

We supply this automation component strictly as a 100% brand new, original factory-sealed unit to guarantee untarnished silver-alloy contacts, uncompromised coil insulation properties, and flawless mechanical armature travel across high-frequency switching cycles.

Technical Specifications

The table below logs the precise electrical ratings, contact behaviors, and design parameters of this plug-in relay:

Engineering Advantages

• Optimizes Rail Density inside Control Panels: The narrow, slim-line chassis profile allows engineers to mount numerous interposing relays side-by-side on a single DIN rail layer. This layout minimizes the horizontal footprint required for control isolation, leaving more room for adjacent PLCs, terminal blocks, or power distribution hardware.

• Simplifies Local Troubleshooting via Dual Visual Indicators: This relay combines a bright internal LED pilot light with a mechanical On/Off indicator window on the outer housing. The LED confirms active coil excitation, while the mechanical flag verifies actual physical armature movement, helping field technicians differentiate between electrical signal failures and stuck mechanical contacts.

• Secures Electrical Connections Against Industrial Vibration: The precision blade terminals slip tightly into mating terminal sockets, while an integrated retainer clip locks the relay body firmly onto the base. This mechanical retention framework stops the relay from walking out of its socket when mounted directly to machinery experiencing continuous, high-amplitude vibrations.

FAQs

• Can I plug this 700-HK32A2-4L relay into any generic relay base socket?

  No. This relay requires a specific 700-HK compatible socket configured for standard blade-style terminals and the 8A DPDT pin footprint. For optimal retention and proper grounding path safety, always install the module together with the designated Allen-Bradley matching socket assembly and its accompanying heavy-duty steel retainer clip.

• Does this model support switching for high-voltage DC load applications?

  The main contacts carry an 8A continuous inductive/resistive rating optimized for 240V AC networks. While the silver-alloy contacts can handle low-voltage DC signals (such as 24V DC logic feedback), switching high-voltage DC loads will cause severe electrical arcing across the open-style contacts. This arcing degrades the contact faces rapidly because DC voltages do not possess a natural zero-crossing point to extinguish the spark.

• How does the LED pilot light react if a technician reverses the input polarity?

  This specific variant operates on a 240V AC alternating current coil at 50/60 Hz. Because alternating current naturally oscillates cycles between positive and negative potentials, input wire polarity across the coil terminals does not affect the operation of the relay or the illumination of the internal diagnostic LED.
