Key Features
OSSD Signal Processing:

Accepts inputs from safety devices with OSSD outputs (e.g., two-channel PNP signals from safety light curtains, laser scanners, or safety switches).

Monitors for faults such as short circuits, cross faults, or device failures.

Safety Function:

Provides dual-channel safety outputs (relay contacts) for controlling machinery power circuits.

Ensures safe torque off (STO) or emergency stop functionality by interrupting power to dangerous actuators.

Compact and Modular Design:

Space-saving form factor for easy integration into control panels.

DIN rail mountable (standard 35 mm rail).

Diagnostic Indicators:

LED status indicators for power, input status, and output status, enabling quick troubleshooting.

Compliance with Safety Standards:

Meets ISO 13849-1 PL e and IEC 61508 SIL 3 requirements, ensuring high reliability for safety-critical applications.

Wide Voltage Range:

Supports 24 V DC supply voltage, typical for industrial control systems.
