Pilz 751102 PNOZ s2 C Safety Relay 24VDC 3NO 1NC Machine Protection

Description

The Pilz 751102 PNOZ s2 C is an ultra-compact, high-performance safety relay from the renowned PNOZsigma series. Operating on a 24 V DC supply, it features 3 safety contacts (Normally Open) and 1 auxiliary feedback contact (Normally Closed). It is specifically designed for evaluating input signals from emergency stop pushbuttons and safety gate switches in industrial control systems.

Safety relays act as the core decision-making element between hazard-detecting inputs and power-isolating outputs. Upon sensing an emergency stop actuation or safety gate opening, the PNOZ s2 C immediately cuts control power to hazardous actuators. For machine builders, panel integrators, and safety compliance engineers in Bangladesh, this German-engineered Pilz safety relay delivers reliable, certified operator protection and international safety compliance.

Key Features

• PNOZsigma Compact Design: Extremely slim housing width (22.5 mm) maximizes space utilization inside industrial control panels.
• Spring-Loaded Push-in Terminals (“C” Variant): Fast, vibration-proof, maintenance-free wiring connection without standard screw tightening.
• Dual-Channel Safety Architecture: Supports single-channel and dual-channel input wiring configurations with cross-circuit detection.
• Multi-Status Diagnostics: Integrated LEDs provide clear diagnostic indication for supply voltage, input status, and switch state.
• Flexible Operating Modes: Selectable manual or automatic reset modes via front-panel rotary switches.

Technical Advantages

• High Safety Standard Rating: Achieves up to PL e (EN ISO 13849-1) and SIL CL 3 (EN IEC 62061) for high-risk applications.
• Durable Construction: Heavy-duty polycarbonate housing built to withstand mechanical vibration and industrial panel environments.
• Advanced Safety Protection: Internal electronic monitoring prevents relay contact welding and line cross-fault failures.
• Energy Saving Operation: Low thermal dissipation limits internal cabinet heat generation and lowers power draw.

• Set the front rotary switch to the appropriate operating mode (Manual/Automatic reset) before applying 24 V DC power.
• Connect safety outputs (NO contacts) in series with the main actuator power contactors.

Maintenance Tips:

• Perform routine safety function testing at least once a year by actuating connected emergency stops and gate sensors.
• Keep the enclosure free of conductive dust, moisture, and chemical contaminants.
• Observe front status LEDs during routine cabinet audits to verify channel switching health.

Safety Instructions:

• Installation and wiring must be carried out exclusively by trained automation safety technicians.
• Always isolate all power feeds (control and power circuits) before attempting wiring modifications.
• Never bypass or short-circuit safety relay contacts.
