• Provides intrinsically safe interfaces, limiting the energy transferred to hazardous areas to prevent explosions.

• Isolates control systems and field devices, preventing fault propagation.

• Conditions and converts signals, ensuring control systems can correctly process field signals.

• Detects field faults (such as short circuits, open circuits) and reports them to the control system.

• Supports various types of field devices, such as sensors, transmitters, actuators, etc.

• Features:

• Complies with various international safety standards (e.g., IEC 61508, ATEX, IECEx).

• Supports different SIL levels (e.g., SIL 2, SIL 3).

• Multiple channel configurations (single channel, dual channel, multi-channel).

• DIN rail mounting.

• Pluggable terminals for easy wiring and maintenance.

• Provides diagnostic functions for easy troubleshooting.
