Key Features
Dual OSSD Input Channels:

Accepts two-channel OSSD inputs (typically PNP signals) from safety devices, providing cross-fault monitoring for enhanced safety integrity.

Detects faults such as short circuits, wire breaks, and device failures.

Safety Relay Outputs:

Provides 2 normally open (NO) safety relay contacts for controlling machinery power circuits.

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

Compact DIN Rail 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 (PWR), input status (IN1, IN2), and output status (OUT), facilitating quick troubleshooting and maintenance.

Compliance with Safety Standards:

Meets ISO 13849-1 PL e (Performance Level e) and IEC 61508 SIL 3 (Safety Integrity Level 3), ensuring compliance with global machinery safety directives.

Wide Operating Voltage Range:

Supports 24 V DC supply voltage (with a typical range of 20.4 V to 28.8 V DC), suitable for industrial environments.

Flexible Configuration:

Allows manual or automatic reset options based on application requirements.
