Pilz Relays

Safety in Every Circuit — the Core of Pilz Engineering

Relays are the invisible backbone of industrial safety. They decide whether a machine starts, stops, or locks into a safe state — and must do so with absolute reliability. Pilz relays are engineered for this purpose: precise, durable, and compliant with the world’s most demanding safety standards. Whether you need compact interface modules, multifunction safety relays, or programmable monitoring systems, Pilz ensures your signals switch correctly, every single time.

Pilz Safety Relays — Proven Protection for Human and Machine

The Pilz safety relay series, most notably PNOZ, set the global benchmark for functional safety.

• Applications: emergency stop monitoring, guard door control, light curtain integration, two-hand operation, and standstill detection.
• Design logic: each unit provides redundant channels, cross-fault detection, and safe outputs (up to PL e / SIL 3).
• Wiring & service: tool-free terminal design and modular coding make them quick to replace during maintenance.
• Product families: PNOZ X for simple functions, PNOZ sigma for space efficiency, PNOZ multi 2 for configurable safety control.

Across machinery and robotics, these relays prevent hazardous motion before it can occur — maintaining both compliance and productivity.

Pilz Monitoring & Control Relays — Diagnostics That Go Beyond Switching

Beyond simple safety logic, Pilz monitoring relays provide supervision of current, voltage, phase sequence, insulation resistance, and standstill.

• Integrated diagnostic LEDs simplify troubleshooting and status reporting.
• Adjustable thresholds and delay settings suit automation panels and drive systems.
• Designed for DIN rail mounting and long mechanical endurance.
• Also used for overload or under-voltage detection, motor phase control, and line integrity checks.

For automation engineers, these relays act as smart sentinels — continuously evaluating power conditions that can compromise uptime.

Pilz Interface & Time Relays — Compact Control for Every Application

To simplify signal adaptation, Pilz interface relays bridge different control voltages (24 V DC, 120 V AC, etc.) and isolate logic circuits from power stages.

• Plug-in relay modules allow quick replacement and modular expansion.
• Ideal for PLC interfacing, drive enable circuits, and actuator control.

Meanwhile, Pilz time relays provide precise delay functions for sequence control: on-delay, off-delay, interval, and flashing modes. Compact housings fit directly on DIN rails, saving space in tight cabinets.

How to Select the Right Pilz Relay for Your Panel

1. Define the function: Is it safety, monitoring, timing, or signal interface?
2. Determine contact configuration: number of channels, normally open/closed, and output type.
3. Check safety level: confirm PL/SIL rating for machine or process requirements.
4. Match voltage and mounting style: Pilz offers universal coil voltages and DIN 35 compatibility.
5. Plan for maintenance: opt for modular base sockets to replace relays without rewiring.

Reliability and Lifecycle Considerations

• All Pilz relay systems undergo 100% functional testing before shipment.
• Service intervals are predictable, with clear LED diagnostics for replacement timing.
• Their mechanical endurance often exceeds 10 million switching cycles.
• By using standardized module widths, panel upgrades remain straightforward even after years of operation.

Integration with Pilz Automation Ecosystem

Pilz relays integrate seamlessly with the brand’s PLCs, I/O modules, and automation controllers, creating a consistent logic layer from input to safety output.

• Compatible with PSS 4000 and myPNOZ architectures.
• Identical labelling and wiring conventions across all Pilz product lines simplify documentation
• The result: a unified control philosophy that supports faster commissioning and easier troubleshooting.
