Pilz 751124 PNOZ s4.1 C Safety Relay Supplier

As a supplier and distributor with pan-India reach, Indus Megamart supports procurement teams, plant engineers, and system integrators who require dependable availability of certified safety control components for compliance-driven applications.

What is Pilz 751124 PNOZ s4.1 C Safety Relay

Pilz 751124 PNOZ s4.1 C Safety Relay is a 24VDC safety monitoring relay with 3 normally open and 1 normally closed output contacts, designed to supervise emergency stop circuits, safety gates, and interlocking devices in industrial machinery. It ensures safe shutdown by monitoring dual-channel safety inputs and controlling safety outputs reliably.

This relay belongs to the PNOZsigma family used for hardwired safety architectures in machinery. It is typically selected where a programmable safety controller is unnecessary and a dedicated safety relay offers a simpler, certifiable, and cost-effective solution. The device monitors dual-channel input circuits, evaluates discrepancies, and drives safety outputs that control contactors, drives, or power isolation circuits. The “C” variant is commonly preferred for its terminal configuration suited to panel wiring in compact control cabinets.

Applications of Pilz 751124 PNOZ s4.1 C Safety Relay

1. Emergency Stop Monitoring in CNC Machines
   Ensures instant de-energization of motion circuits when E-stop is activated.
2. Safety Gate Monitoring in Packaging Lines
   Prevents machine restart when access doors are open.
3. Two-hand Control Stations in Press Machines
   Validates simultaneous actuation for operator safety.
4. Conveyor Interlock Systems
   Stops material flow when protective guards are removed.
5. Hydraulic Power Pack Safety Circuits
   Controls pump shutdown during abnormal access or emergency events.
6. Robotic Work Cell Perimeter Protection
   Interfaces with safety switches and light curtains for safe access control.
7. Test Benches and Industrial Rigs
   Provides dedicated safety logic without PLC dependency.

FAQs

What does Pilz 751124 PNOZ s4.1 C Safety Relay monitor?

It monitors dual-channel safety inputs from emergency stops, safety gates, and interlocks and controls safety outputs that de-energize machinery during unsafe conditions.

Is this relay suitable for replacing older PNOZ models?

Yes, it is often used as a modern replacement where output configuration and wiring compatibility match the existing safety circuit.

Can it be used without a safety PLC?

Yes. It is designed for hardwired safety logic where a dedicated relay is sufficient without programmable safety control.

What devices can be connected to its inputs?

E-stop buttons, safety gate switches, two-hand control stations, and safety sensors are commonly connected.

Why are spring terminals preferred in the C variant?

They simplify wiring in dense panels and reduce maintenance time during installation.

How is reset configured in this relay?

Reset wiring can be configured as manual or automatic depending on safety requirements.

Does this relay require periodic maintenance?

Routine inspection of wiring, terminals, and feedback loop integrity is recommended during panel maintenance.
