Description
The Honeywell FC-TSDI-1624 is a 16-channel digital input field termination assembly for connecting external 24 VDC discrete signals to compatible Safety Manager input modules. It provides field wiring terminals, a system interconnection interface, and PTC-based current limiting. The FC variant is identified as conformal coated, distinguishing it from the non-conformal-coated FS variant.
Product Identification
| Parameter | Specification |
|---|---|
| Model | FC-TSDI-1624 |
| Brand | Honeywell |
| Product Type | Digital Input Field Termination Assembly |
| System Interface | SICC-0001/Lx interconnection cable |
| Associated Input Module | SDI-1624 |
| Coating | Conformal coated |
| Input Channel Count | 16 |
Electrical Interface and Protection
The assembly connects field wiring to the associated digital input modules through a system interconnection cable. Its field-side terminals accept discrete input wiring, while the PTC elements limit current under specified fault conditions.
| Parameter | Specification |
|---|---|
| Nominal Field Voltage | 24 VDC |
| Input Voltage Range | 24 VDC, -15% to +30% |
| Maximum Input Current | 15 mA at 24 VDC, with a redundant pair of SDI-1624 modules as the load |
| PTC Resistance | 260 ohm +/- 25% at 25 deg C |
| Typical PTC Steady Current | 45 mA +/- 35% at 24 VDC |
The PTC protection helps prevent a field-wire short to 0 V from pulling down the shared supply for all 16 channels. The assembly provides termination and circuit protection; input signal processing remains the responsibility of the associated SDI-1624 modules.
Mechanical and Wiring Data
| Parameter | Specification |
|---|---|
| Field Terminals | Screw terminals |
| Maximum Wire Size | 2.5 mm2 (AWG 14) |
| Wire Strip Length | 7 mm |
| Terminal Tightening Torque | 0.5 Nm |
| DIN Rail Types | TS32 or TS35 x 7.5 |
| Rail Length Used | 91 mm |
| Dimensions (L x W x H) | 90 x 70 x 58 mm |
Installation Considerations
- Install on a compatible TS32 or TS35 x 7.5 DIN rail.
- Prepare field conductors to the specified wire size and strip length.
- Tighten screw terminals to 0.5 Nm.
- Verify the SICC-0001/Lx cable and SDI-1624 module configuration before connecting field wiring.
- Confirm the applicable hardware revision and site wiring requirements before replacing an installed assembly.
Frequently Asked Questions
Q: Does the FC-TSDI-1624 process digital input signals independently?
A: No. It terminates field wiring and interfaces with the associated SDI-1624 modules. It is not a standalone signal-processing module.
Q: What distinguishes the FC-TSDI-1624 from the FS-TSDI-1624?
A: The FC variant is identified as conformal coated, while the FS variant is identified as non-conformal coated. Verify the required coating and complete part number when selecting a replacement.
Q: What field wiring limits should be checked before installation?
A: Check the maximum conductor size of 2.5 mm2 (AWG 14), the 7 mm strip length, and the 0.5 Nm terminal tightening torque. Also confirm the applicable interconnection cable and input-module configuration.
