Performance comparison
Parameter | FBM12 | FBM07 | FBM24/FBM27 |
Voltage Input | 15–240 V AC/DC | 15–130 V DC | 125–240 V DC |
Contact Sense | Yes | Yes | Yes |
Isolation | High-level isolation | Channel-isolated | High-level isolation |
Redundancy Support | Optional | Optional | Optional |
Summary:
FBM07 and FBM12 both support contact inputs, but FBM12 extends to voltage levels up to 240 V. FBM24 and FBM27 focus on higher voltage ranges, while FBM12 is a robust all-rounder.
Typical cooperation cases
Germany – Petrochemical Plant Automation
FBM12 modules installed for high-voltage contact detection in safety interlocks. Redundant installation minimized control interruptions.
China – Urban Subway Ventilation System
Used to monitor ventilation fan status and emergency door contacts. High isolation ensured reliable operation under moisture and vibration conditions.
United States – Water Treatment Facility
Deployed in pump stations to sense AC voltage line faults. Hot-swappable design allowed field maintenance without service disruption.
