FS-TDO-1624 | Honeywell Safe Digital Output FTA (16 CH, 24 VDC)

Product Overview

The Honeywell FS-TDO-1624 is a Safe Digital Output Field Termination Assembly (FTA) providing 16 channels of 24 VDC digital output for Honeywell Safety Manager systems. With double the channel density of standard 8-channel FTAs, this module maximizes I/O capacity in space-constrained control panels while maintaining SIL-rated safety integrity for actuator control applications.

Key Features

• 16 Digital Output Channels: High-density 24 VDC output for maximum panel efficiency
• Short-Circuit Protection: Per-channel electronic protection with automatic reset
• System Interconnection: SIC cable interface to DO-1624 I/O modules
• Status LEDs: Per-channel indication for output state and fault diagnostics
• DIN Rail Mounting: Universal snap-in for TS32/TS35 rails

Installation Guide

1. DIN Rail Mount: Snap FTA onto TS32/TS35 rail
2. Actuator Wiring: Connect up to 16 field actuators to screw terminals
3. Power Calculation: Verify total load current against power supply capacity
4. SIC Cable: Connect to DO-1624 I/O module in chassis
5. Load Balancing: Distribute high-current loads across multiple FTAs if needed

FAQ

Q: What is the advantage of 16 channels vs. 8 channels?
A: The 16-channel design reduces panel space and wiring complexity for applications with many actuators, though total current capacity must be verified.

Q: Can all 16 channels operate simultaneously?
A: Yes, but total current draw must not exceed the module's aggregate rating and power supply capacity.

Selection Tips

• Use for high-density actuator applications to minimize panel footprint
• Calculate total power budget carefully with 16 channels
• Ensure paired I/O module is DO-1624
