III. Functions and Safety Features

Fault safety: Contacts safely open when power is lost / in case of failure to ensure safe shutdown.

Short-circuit protection: Each output can withstand short circuits without damaging the module.

Self-diagnosis: Full coverage diagnosis for coil / contact faults, short circuits, open circuits.

Status indication: LED per channel, power / fault LED, intuitive maintenance.

Redundancy compatibility: Supports QMR/TMR, meeting high safety redundancy architecture.

IV. Typical Applications

ESD emergency stop: Critical valves, actuator control

BMS boiler management: Fuel valve, igniter, purge valve

F&G fire protection system: Alarm horn, sprinkler valve, fire door interlock

Safety interlock: Third-party dry contact interface, low-power load drive

V. Comparison within the Series (Key Distinctions)
