• Entity Parameters ensure intrinsic safety with Uo=25V, Io=147mA, Po=0.92W limits.
• These certifications guarantee safe operation in the most demanding environments.

Control Logic Operation

• Control Input 0 + Override 0 = Output OFF (normal off state)
• Control Input 0 + Override 1 = Output ON (override active)
• Control Input 1 + Override 0 = Output OFF (safety priority)
• Control Input 1 + Override 1 = Output OFF (maximum safety)
• This logic ensures safety override always takes priority over normal control.

Industrial Applications

• Solenoid valve control in hazardous process applications
• Hazardous area alarm and warning system activation
• Emergency shutdown systems for critical safety protection
• Process safety interlocks in chemical and petrochemical plants
