I/O modules

The Honeywell FC-TSDI-1624 is a Safe Digital Input Field Termination Assembly (FTA) engineered for hazardous locations and demanding industrial applications. It serves as an interface between the system interconnection cable (SICC-0001/Lx) and external field wiring, ensuring secure, stable, and reliable transmission of digital input signals.

Key Features

• Provides a safe and efficient interface between SICC cables and external field wiring via screw terminals.
• Designed for Class I, Division 2 Hazardous Locations environments.
• Equipped with PTC resistor protection to prevent loss of all 16 channels in case of a short circuit.
• DIN rail snap-in design allows quick installation and easy maintenance.
• Supports redundant SDI-1624 modules for enhanced load balancing and system reliability.
