Honeywell FS-TSDO-0824 SIL 2 8-Channel Safe Digital Output Module

Product Description

Overview

The Honeywell FS-TSDO-0824 is a high-integrity digital output module engineered for safety-critical automation systems. Designed for integration within the Honeywell Safety Manager (Fail Safe) architecture, this module provides 8 isolated output channels capable of controlling solenoids, actuators, and relays while maintaining fail-safe operation. It is certified for SIL 2 and ensures that any fault condition forces outputs to a predefined safe state.

Key Features

High Reliability and Diagnostics

• Monitors internal circuits and field wiring for shorts, open circuits, and cross-channel interference

• Includes watchdog timers for self-checking critical components

• Diagnostic LEDs for Run, Fail, and individual channel status

Output Specifications

• 8 independent digital output channels

• Nominal voltage: 24 VDC (maximum 36 VDC)

• Current capacity: up to 2 A per channel (load-dependent)

• Galvanic isolation between logic and field circuits for surge protection

Fail-Safe and Redundancy

• Executes automatic safe shutdown on communication loss or critical fault

• Supports redundant pairing for increased system availability

• Hot-swappable in redundant configurations to minimize downtime

Industrial-Grade Design

• Operating temperature: -40°C to +75°C

• DIN rail (TS32 / TS35 x 7.5) or panel mount

• Robust against electromagnetic interference (EMI) and harsh environments

• Compact dimensions: 60 × 70 × 58 mm (D × W × H)

Technical Specifications Table

Applications

The FS-TSDO-0824 is suitable for critical SIS loops including Emergency Shutdown (ESD), Fire and Gas (F&G), and other high-integrity process control systems. Its fast, reliable outputs and fail-safe design make it ideal for scenarios requiring SIL-certified operation.

FAQ

Q: Can this module be used in SIL 3 systems?
A: Yes, it can be configured in redundant pairs to meet higher SIL requirements, although individually it is SIL 2 certified.

Q: Is it safe to replace this module while the system is running?
A: Hot-swapping is supported only when configured redundantly to maintain continuous operation.

Q: What loads can each output channel drive?
A: Each channel supports up to 2 A, suitable for solenoids, relays, and small actuators.

Q: How do I monitor the module status?
A: Front-panel LEDs indicate system Run, Fail, and individual channel conditions for rapid diagnostics.
