Pilz 24V ac/dc Safety Relay, 3 Safety Contacts, 1 Auxiliary Contact, Screw Terminal, DIN Rail Mount, Model 774300

Pilz 774300 24V ac/dc Safety Relay is a single channel safety relay designed for reliable control of safety circuits in industrial, manufacturing, and automation environments. The device features three safety contacts (3 NO/1 NC) and one auxiliary contact along with screw terminal connections for secure wiring.

The relay supports both automatic and manual reset methods, allowing flexible operation based on system requirements. Its robust DIN rail mounting makes installation straightforward in electrical panels and control cabinets.

With a low power consumption of 2.0W, the unit operates efficiently at coil voltages of 24V ac/dc. It switches DC voltages up to 24V and AC voltages up to 240V at a contact current rating of 6A, suited for varied industrial loads.

Designed to meet stringent standards including EN 60947-1, EN ISO 13849-1, EN IEC 62061, and IEC 61511 SIL 3, the safety relay delivers high reliability and safety. It automatically tests correct opening and closing of its contacts during each on/off cycle and retains full functionality even if component faults occur.

The device functions effectively across a broad ambient temperature range from -10°C to 55°C and has an IP rating covering IP54, IP40, and IP20 for protection against dust and moisture. Its compact form factor with dimensions 121mm (H) x 87mm (L) x 22.5mm (W) allows easy integration into control systems where space is at a premium.

Typical applications include mechanical and hydraulic presses, general safety circuits compliant with EN 60204-1, emergency stop button circuits, and safety curtains, providing essential protection for personnel and equipment.

The relay monitors itself and checks safety functions to ensure ongoing protection. LED indicators enable clear monitoring of channel status and supply voltage. Single or dual channel input operation supports flexible safety circuit configurations.

Durable construction affords extended operational life compared to alternatives. Standard DIN rail mount simplifies installation in industrial control panels. Country of Origin: China. Explore more in the Safety Relay category at EnvMart for comprehensive industrial automation safety solutions.
