FTA-T-08 | Honeywell | 3410713 Sortie numérique à sécurité intégrée Honeywell (contact relais) FTA (4 canaux)

Description

Engineered for high-integrity safety systems, the Honeywell FTA-T-08 is a 4-channel fail-safe digital output relay Field Termination Assembly (FTA). Designed to interface directly with safety-critical control modules such as the 10201/2/1, this unit provides robust galvanic isolation and contact multiplication for critical process shutdown and safety interlock loops. Each of the four channels features a redundant, diverse relay configuration utilizing devices from different manufacturers to mitigate common-cause failures and comply with rigorous functional safety requirements.

The FTA-T-08 incorporates an integrated 3.15 AT slow-acting fuse on each normally open (NO) field contact, protecting field-side wiring and devices from unexpected overcurrent conditions. Local status diagnostics are indicated through on-board LEDs, facilitating prompt field troubleshooting. Connection to the primary controller rack is accomplished using specialized SIC-C-02 cables, maintaining optimal signal integrity across the termination assembly.

Features

• Four independent fail-safe digital output relay channels.
• Redundant contact architecture featuring diverse relays from separate manufacturers to prevent common-mode failures.
• Individual channel protection via 3.15 AT slow-acting fuses on the output contacts.
• Integrated diagnostic LEDs for real-time channel status monitoring.
• Silver alloy contacts designed for reliable and durable switching.
• Direct integration compatibility with Honeywell 10201/2/1 modules using SIC-C-02 cable assemblies.

Applications

• Emergency Shutdown Systems (ESD) in petrochemical and refinery environments.
• Burner Management Systems (BMS) in power utility plants.
• Fire and Gas (F&G) mitigation control networks.
• Critical safety interlock loops in chemical processing.

Installation Guidelines

• De-energize all power sources before handling, mounting, or wiring the Field Termination Assembly.
• Mount the module securely on a standard DIN rail or enclosure backplate inside a dust-free, dry industrial cabinet.
• Isolate and route the high-voltage relay wiring separately from low-voltage logic signal cables.
• Confirm that the field load does not exceed the maximum rated capacity of the 3.15 AT internal fuses.
• Maintain sufficient spacing between adjacent modules to ensure continuous convection cooling within the specified ambient temperature limits.
