Apollo Marine DIN-Rail Input/Output Unit (55000-774MAR)

The Apollo Marine DIN-Rail Input/Output Unit (55000-774MAR) provides a reliable interface between a marine fire alarm system and external equipment. The unit combines a voltage-free single-pole changeover relay output, a single monitored switch input, and an unmonitored non-polarised opto-coupled input, making it fitting for a wide range of monitoring and control applications in marine environments.

The 55000-774MAR monitors connected switch circuits and can report fault, switch open, and switch closed conditions to the fire alarm control panel. This helps provide accurate monitoring of connected equipment and system status.

The unit can switch loads of up to 8A at 250V AC, making it fitting for controlling a variety of marine and building service equipment. Three visible LEDs provide clear local status indication, enabling installers and maintenance personnel to quickly identify the operating condition of the unit.

Designed for DIN-rail installation, the module mounts directly onto a standard 35 mm DIN rail, allowing easy installation within marine control panels and electrical enclosures.
