Allen Bradley 700-HN128 Bulletin 700 14-Blade Relay Socket

Product Overview

The Allen Bradley 700-HN128 provides a robust electrical and mechanical interface for Bulletin 700 industrial relays. This 14-blade socket facilitates the rapid installation and replacement of plug-in relays within control panels without disturbing fixed field wiring. We supply this unit as 100% Brand New original factory stock, ensuring the high-conductivity contact points and dielectric strength required for long-term industrial service.

Technical Specifications

The 700-HN128 utilizes a high-density blade arrangement to support multi-pole relay configurations in a compact footprint.

Engineering Advantages

• Optimized for High-Density Wiring: The 14-blade configuration supports 4-pole (4PDT) relay switching within a slim profile. This architecture maximizes I/O density on the DIN rail, allowing engineers to squeeze more control logic into constrained enclosure spaces.

• Open-Style Terminal Accessibility: The open-style terminal design provides clear visibility and tool access for wiring. This physical layout accelerates the installation process and simplifies torque verification during routine maintenance inspections.

• Secure Mechanical Retention: The socket's internal blade receptacles exert high contact pressure on the relay pins. This mechanical grip prevents the relay from shaking loose in high-vibration environments, such as those found near heavy machining centers or on mobile industrial skids.

• Standardized Component Integration: The 700-HN128 integrates seamlessly with 700-HC (General Purpose) and 700-SC (Safety) relays. This standardization reduces the variety of spare parts a facility must stock, simplifying inventory management for large-scale automation projects.

FAQs

• Which relays fit into the 700-HN128 socket?

  This socket specifically accepts Allen Bradley Bulletin 700-HC and 700-SC series relays that feature a 14-blade pin configuration. Always match the blade count and pin pattern of the relay to the socket before attempting installation.

• What is the maximum current capacity of the screw terminals?

  The 700-HN128 supports a continuous current rating of up to 10 Amps at 300V AC. Exceeding this amperage may cause localized overheating at the terminal points and compromise the structural integrity of the plastic housing.

• Can I mount this socket on a standard DIN rail?

  Yes. The 700-HN128 snaps directly onto standard 35mm DIN rails. It also typically includes mounting holes for direct-to-panel screw installation if a DIN rail is not available.

• Does this socket require a separate retaining clip?

  While the socket provides a secure friction fit, we recommend using a 700-HN series retaining clip (sold separately) for applications subject to extreme vibration or for relays mounted in an inverted or horizontal orientation.
