Key Features

Safe isolation
Physically isolates the hazardous field side from the system side, effectively suppressing interference and ensuring the independence of safety circuits.

Comprehensive diagnostics
Automatic testing of switch status, line integrity, crosstalk, and input filtering. Fault conditions can be directly linked to control system alarms and safety interlocks.

Flexible adaptation
Compatible with two-wire proximity switches and dry contacts, suitable for Zone 2 explosion-proof applications.

Plug and play integration
Precisely matched to the HIMatrix backplane, significantly reducing cabinet wiring, installation effort, and commissioning time.
