Overview
Configured for discrete signal interfacing in Honeywell safety and automation platforms, the Honeywell FC-GMLD16 (FC-GMLD16 Digital I/O Module) provides 16 channels for dry-contact or voltage input signals. The module processes field discrete states and transfers them through the associated control system interface.

Channel Isolation and Process Signal Handling
The Honeywell FC-GMLD16 accepts discrete field states through 16 input channels. The supplied data identifies both dry-contact and voltage-input operation, allowing the channel interface to accommodate different discrete field signal arrangements.
The module uses a 24 VDC nominal input level. It provides a specified response time of <= 10 ms, supporting discrete state detection within the associated control-system scan and processing path.
The supplied specifications also identify galvanic isolation for related Honeywell digital input configurations. However, the available data does not explicitly assign a channel-to-channel isolation rating to the FC-GMLD16 itself. Therefore, no specific isolation voltage or channel isolation value is stated here.

Field Installation Guidelines
Mount the FC-GMLD16 in the designated Honeywell rack, chassis, or field termination arrangement. Verify the mechanical interface before installation.
Connect each field discrete signal to its assigned channel according to the system wiring documentation. Keep field signal wiring separated from high-voltage power conductors and other sources of electrical interference.
For shielded signal cables, terminate and ground the shield according to the applicable Honeywell system grounding design. Avoid creating unintended ground loops.
Before energizing the circuit, verify input polarity, terminal assignment, field voltage, and wiring continuity. Confirm that the connected field device matches the configured input type.
Do not apply a field voltage outside the specified system design. Also, verify the applicable rack or enclosure temperature and environmental limits before commissioning.
