- 24-Channel Density: High channel count per module slot reduces chassis footprint and wiring complexity in large SIS cabinets
- Integrated Diagnostics: Continuous self-test routines detect open-circuit, short-circuit, and stuck-at faults without process interruption
- Seamless SMSC Integration: Native backplane communication with Safety Manager SC controller eliminates gateway latency and simplifies safety function configuration in Safety Builder engineering tool
- Hot-Swap Capability: Supports module replacement under power in redundant configurations, maximizing system availability
- Proven Field Record: Deployed globally in thousands of SIS installations across major EPC contractors and end-user facilities
System Architecture & Signal Flow
The FS-TIDI-1624 resides in the Safety Manager SC I/O chassis and communicates via the proprietary SMSC safety backplane to the SM SC controller. Field wiring connects to the module’s terminal block (or marshalling panel via cable assembly). Each input channel passes through:
- Field Terminal → Galvanic isolation barrier
- Signal conditioning & filtering → Analog-to-digital conversion
- Diagnostic engine (open/short/stuck-at detection)
- Safety backplane → SM SC controller safety logic execution
- Safety function output → Final element actuation
The module supports 1oo1, 1oo2, and 2oo3 voting architectures as configured in the Safety Manager SC application logic, enabling flexible SIL achievement strategies.

Technical FAQ
Q: Is the FS-TIDI-1624 compatible with the original Safety Manager (SM) platform, or only Safety Manager SC?
A: The FS-TIDI-1624 is designed for the Safety Manager SC (SMSC) platform. It is not directly interchangeable with legacy SM modules. Verify your chassis and controller revision before ordering.
Q: Can this module achieve SIL 3 in a single-module configuration?
A: SIL 3 is typically achieved through redundant module configurations (e.g., 1oo2D or 2oo3). Consult the Honeywell Safety Manager SC System Manual and your SIL verification report for the specific architecture required.
Q: What firmware version is required for full diagnostic functionality?
A: Firmware compatibility depends on the SM SC controller version. Konmask will provide the firmware revision of the supplied module; consult Honeywell’s compatibility matrix or contact our technical team for guidance.
Q: Do you provide the Honeywell Safety Builder configuration files or application logic?
A: We supply hardware only. Safety Builder software licenses and application engineering are the responsibility of the end-user or their system integrator.
Q: What is the typical lead time for in-stock units?
A: In-stock units ship within 3–5 business days after PO confirmation. For large quantities or specific condition grades, lead time is confirmed at quotation stage.
