Honeywell FC-TSDI-1624C – 16-Channel Digital Input Field Termination Assembly | Experion PKS DCS Platform
Engineering Background
The FC-TSDI-1624C is a factory-engineered Field Termination Assembly (FTA) developed by Honeywell Process Solutions as an integral component of the Experion® Process Knowledge System (PKS) distributed control architecture. Designed to serve as the hardwired interface between field instrumentation and the C300 Controller I/O subsystem, this module eliminates the need for custom marshalling panels and reduces wiring complexity in large-scale process plants.
Product Positioning
Targeted at procurement engineers and system integrators managing brownfield upgrades or greenfield DCS deployments, the FC-TSDI-1624C provides a standardized, plug-and-play termination solution for 16 discrete digital input channels operating at 24 VDC. Its DIN-rail-mountable form factor and pre-wired screw terminal blocks accelerate commissioning timelines and reduce field wiring errors in critical process environments including refining, petrochemical, power generation, and pharmaceutical manufacturing.

- High Channel Density: 16 DI channels per FTA maximizes cabinet space utilization in high-I/O-count projects
- Robust Signal Conditioning: Onboard filtering and isolation protect controller backplane from field-side transients and ground loops
- Long-Term Availability: Honeywell PKS Series C platform has an extended lifecycle roadmap; spare parts availability is well-documented
- Brownfield Compatibility: Drop-in replacement for existing FC-TSDI-1624C installations without re-engineering the I/O subsystem
System Architecture & Signal Flow
In a typical Experion PKS deployment, the FC-TSDI-1624C is mounted in the I/O cabinet and connected to the Series C Digital Input I/O module via a pre-wired cable assembly. Field instrument cables terminate at the FTA screw blocks, where signal conditioning and isolation are applied before the discrete state is transmitted over the C-Bus to the C300 Controller. The controller then processes the digital state within the Experion PKS control strategy and communicates status to the Experion Station HMI via the FTE (Fault Tolerant Ethernet) network.

Technical FAQ
Q: Is the FC-TSDI-1624C compatible with Honeywell HC900 or Safety Manager controllers?
A: No. The FC-TSDI-1624C is specifically designed for the Experion PKS Series C I/O subsystem and is not interchangeable with HC900 or Safety Manager platforms.
Q: Can this FTA be used with third-party I/O modules?
A: The FC-TSDI-1624C is engineered exclusively for Honeywell Series C I/O modules. Use with non-Honeywell modules is not supported and may result in signal integrity issues.
Q: What is the difference between FC-TSDI-1624C and FC-TSDI-1624?
A: The “-C” suffix denotes the Series C revision, which includes updated connector specifications and enhanced EMC compliance. Always confirm the revision suffix matches your installed I/O module generation.
Q: Do you provide expedited shipping for shutdown/turnaround projects?
A: Yes. Contact us directly at +0086 19859288691 for emergency procurement support with same-day quotation and priority dispatch.
Q: Is a datasheet or wiring diagram available?
