Description
The Honeywell SDI-1624 CC V1.1 is a 16-channel Safe Digital Input Module used in Honeywell Safety Manager systems. It provides 24 VDC digital input processing for safety-related field signals and is designed for integration into the Safety Manager I/O architecture. Honeywell documentation identifies the SDI-1624 as a 16-channel, 24 VDC safe digital input module.
The CC V1.1 designation identifies the conformal-coated version. Honeywell certification documentation lists FC-SDI-1624, catalog number 3432110, as the 24 VDC, 16-channel conformal-coated safe digital input module with revision CC V1.1.

⚙️ Application
The SDI-1624 is designed to acquire discrete 24 VDC field signals within Honeywell Safety Manager safety-system installations. The module provides 16 digital input channels, with Honeywell specifying a typical 10 ms input delay. The documented input threshold is greater than 15 VDC for HIGH and less than 9 VDC for LOW.
Typical applications include:
- Safety instrumented system digital inputs
- Emergency shutdown and trip signals
- Safety interlock monitoring
- Field contact/status monitoring
- Honeywell Safety Manager I/O replacement
- Industrial process safety applications
For the documented SDI-1624 hardware, power requirements include 5 VDC at 8 mA and 24 VDC internal/external supply requirements of 110 mA. The module occupies approximately 4 TE × 3 HE (4 HP × 3U) of rack space.
🔧 Replacement Notes
When sourcing a replacement, match the complete SDI-1624 CC V1.1 identification rather than relying only on the base SDI-1624 designation. Honeywell documentation distinguishes the standard FS-SDI-1624 from the conformal-coated FC-SDI-1624, and specifically lists 3432110 for the CC V1.1 version.
Confirm the module revision, catalog number, terminal arrangement, Safety Manager chassis configuration, and field wiring before installation. The exact hardware marking on the physical module should take priority when matching a replacement.
