Pilz 750103 PNOZ s3 Safety Relay 24VDC 2NO E-Stop Machine Protection

Description

The Pilz 750103 PNOZ s3 is an ultra-compact, high-performance safety relay belonging to the flagship PNOZsigma product series. Operating on a 24 V DC supply voltage, it features 2 Normally Open (NO) safety output contacts engineered for evaluating input signals from emergency stop buttons, safety gates, limit switches, and light beam devices.

Safety relays serve as the core decision-making components between hazard-detecting sensors and primary power actuators. Upon receiving an emergency stop command or gate open signal, the PNOZ s3 immediately cuts power to hazardous machinery drives. Designed with an ultra-slim enclosure width of just 12.5 mm, selectable operating modes (manual or automatic reset), and a tamper-proof transparent cover, the PNOZ s3 combines maximum safety with unmatched space efficiency. For control engineers, panel integrators, and plant managers across Bangladesh, this German-engineered Pilz safety relay guarantees reliable operator protection and complete peace of mind.

Installation & Maintenance Guide

Installation Requirements:

• Snap the module vertically onto a standard top hat 35 mm DIN rail inside a protective control cabinet (minimum IP54 rated).
• Ensure adequate vertical clearance above and below the 12.5 mm module for natural air circulation.
• Wire input sensors (E-stop pushbuttons, gate switches, or light grids) to screw terminals according to Pilz wiring schematics.
• Select the required reset mode (Manual or Automatic) on the rotary switch and close the protective transparent front cover.

Maintenance Tips:

• Perform routine safety functional testing at least annually by actuating connected emergency stop switches and checking output de-energization.
• Keep ventilation slots clean and free of industrial dust, oil residue, or textile fibers.
• Periodically verify screw terminal tightness to prevent loose connections caused by machinery vibration.

Safety Instructions:

• Installation and wiring must be carried out exclusively by trained automation safety technicians or electrical engineers.
• Always isolate control power and primary lines before touching terminal wiring or opening the front cover.
• Output safety contacts must never be bypassed or short-circuited under any circumstances.
