Pilz Safety Relay PNOZ s2, 24V DC, 3 Safety Contacts, DIN Rail, IP54, Model 750102

The Pilz PNOZ s2 Safety Relay, model 750102, is designed to provide reliable safety control and monitoring in industrial circuits. This relay integrates three normally open (NO) safety contacts and one normally closed (NC) auxiliary contact, supporting complex safety functions required on production lines, conveyors, and a wide range of automated equipment.

It operates with a 24V DC coil voltage and consumes a modest 2W of power, making it suitable for continuous use while maintaining energy efficiency. The compact construction allows for easy installation onto a DIN rail, with screw terminals ensuring secure and straightforward electrical connections. Rated IP54, the relay is protected against dust and splashes, enabling dependable operation in industrial environments.

A highly visible LED display indicates supply voltage, input channel status, switch status of contacts, reset circuit activity, and errors. Rotary switches enable configuration and adjustment of operating modes to meet specific application requirements. Safety features include built-in self-monitoring, electronic fuse protection to avoid short circuits, and automatic testing of contacts on each operating cycle to guarantee effective isolation and response.

With a minimum operating temperature of -10°C and a maximum of 55°C, this relay is suitable for many industrial applications including emergency stop (E-STOP) systems, safety gate limit switches, and reset controls. It complies with major international safety standards, including VDE 0113-1, EN ISO 13849-1, EN IEC 62061, EN 60204-1, EN 954-1, IEC 61511, and EN 60947-5-1, ensuring compatibility across regulated environments.

The relay is particularly valuable in environments where machinery safety, personnel protection, and compliance are paramount - such as manufacturing plants, industrial automation, material handling, and process industries. Its compact footprint (120 x 102 x 17.5 mm) makes it ideal for cabinet installation where space is limited. Designed for Category 4 safety requirements, the relay ensures high-integrity separation and monitored switching of safety circuits.

Reliable monitoring and isolation functionality as part of industrial safety circuits. Supports E-STOP pushbuttons, safety gate switches, and reset buttons for comprehensive protection. Electronic fuse prevents short circuiting, and automatic cycle testing enhances operational safety.

LED interface allows quick visual checks of operating state and fault indication. Efficient configuration with rotary switches to tailor operation mode to system requirements. Screw-type terminals facilitate strong, secure wiring for maintenance simplicity.

Wide application in industrial automation, manufacturing, and process engineering sectors.
