Pilz PNOZ s3 24V DC Safety Relay, 2 Safety Contacts, DIN Rail, IP54, 2.5W, Model 750103

The Pilz PNOZ s3 Safety Relay, Model 750103, is an advanced industrial safety device engineered for monitoring safety-related functions within automation systems. Designed to operate with a 24V DC coil voltage, this relay provides 2 immediate safety contacts and 1 auxiliary contact, enabling seamless integration into emergency stop, safety gate, or light barrier circuits where personnel protection is a priority.

Built to DIN rail mounting standards, the relay has a slim 17.5 mm form factor, making it ideal for compact control panels and multi-relay installations. Its IP54 rating ensures durability against dust ingress and splashes, suited to demanding electrical, automation, and manufacturing environments. The device supports a power consumption of just 2.5 watts, facilitating energy-efficient operation in continuous-use industrial scenarios.

The PNOZ s3 relay incorporates intuitive LED displays for constant status monitoring, including supply voltage, input channels, contact status, reset circuit and error detection. Rotary switches allow the user to configure its operation, while the self-monitoring circuitry automatically tests relay contacts at each cycle for reliable isolation and failsafe performance.

Connection is facilitated by plug-in screw terminals, allowing fast, robust wiring and maintenance. The device is compliant with international safety standards VDE 0113-1, EN 60947-5-1, and EN 60204-1, making it a trusted solution in global factory automation projects.

This relay is widely applied in E-STOP pushbutton circuits, safety gate limit switch monitoring, reset button chains, and optoelectronic safety device networks in settings such as automated assembly lines, material handling, packaging systems, and industrial machinery control panels. Operating temperatures extend from -10°C to +55°C, further enabling deployment in challenging ambient conditions.
