The Honeywell FS-DO-1624 Digital Output Module is an industrial 16-channel 24 VDC non-safety digital output module used in Honeywell Safety Manager / FC-series I/O architectures.
It is designed to convert control system logic signals into discrete ON/OFF outputs for driving field devices such as relays, solenoids, alarms, and indicator loads. The module is widely used in process control and safety-adjacent automation systems where reliable digital switching is required.
It belongs to Honeywell’s FC/FS I/O family, where “FS” typically indicates non-conformal coated standard industrial modules and “FC” indicates conformal-coated versions for harsher environments.
