Honeywell 05704-A-0133 Fire Relay Interface Assembly

Description

Designed for seamless integration within safety monitoring architectures, the Honeywell 05704-A-0133 serves as a highly configurable Fire Relay Interface Assembly. This module consists of an Expansion Relay Card fitted directly onto a Hex Relay Interface Card, providing comprehensive signaling capabilities for industrial monitoring systems. It acts as a rugged interface between logic controllers and field alarm devices, enabling flexible contact switching across diverse electrical environments.

The Honeywell 05704-A-0133 incorporates multiple relay contact styles to accommodate various load requirements. Users can configure individual relay actions to adapt to specific system demands, selecting between latching or non-latching states as well as normally energised or normally de-energised states. High-quality field terminals facilitate secure termination for heavy-duty field cabling, ensuring long-term operational integrity in critical safety configurations.

Features

• Dual-card configuration consisting of an Expansion Relay Card mated to a Hex Relay Interface Card.
• Comprehensive contact arrays featuring 10 x SPCO (Single Pole Change Over), 4 x SPST (Single Pole Single Throw), and 2 x DPCO (Double Pole Change Over) relays.
• User-selectable relay configurations, supporting latching/non-latching and energised/de-energised logic.
• High-capacity contact performance rated for up to 5A at 110V/250V AC and 5A at 32V DC under non-inductive loads.
• Integrated field terminal blocks rated for conductors up to 2.5 mm² (14 AWG).

Applications

• Industrial fire and gas detection networks.
• Emergency shutdown (ESD) signaling and alarming systems.
• Process safety interlocks and hazard mitigation controls.
• Control room annunciator panel routing.

Installation Guidelines

• Isolate all power sources before mounting or servicing the assembly.
• Ensure the card assembly is correctly aligned and seated firmly into its designated rack slot or backplane interface.
• Use suitable crimp ferrules on all field-wire terminations to ensure robust connectivity and prevent wire strand separation.
• Separate low-voltage signal wiring from high-voltage relay switching lines to avoid inductive noise interference.
