Description
The Pilz PNOZ S7.1 (Order No. 750167) is a contact expansion module designed for the PNOZsigma series of safety relays. This module is engineered to provide three additional, safety-related normally open (NO) contacts, effectively extending the control capacity of the main safety relay. It is a critical component for expanding safety circuits in complex machinery, allowing control of more safety actuators like contactors or valves. The module operates on 24V DC and is designed to be used in conjunction with PNOZsigma control units. Its compact, 17.5mm width makes it ideal for installation in control cabinets with limited space. It features a cascade function, enabling it to be connected in series with other PNOZsigma modules (like the S7.2) to form a chain of expanded safety outputs.
Key Features
- Function: Contact expansion module providing 3 safety NO contacts.
- Dependence: Must be used with a PNOZsigma control unit (e.g., PNOZ S4, PNOZ S5).
- Power Supply: 24V DC (supplied via connection to the control unit).
- Mounting: Standard 35mm DIN rail mounting.
- Cascading: Features cascade function for connecting further expansion modules.
- Connection: Uses PNOZ sigma connectors (e.g., 750020) for quick connection to the control unit, simplifying wiring.
- Compact Design: Only 17.5mm wide, saving cabinet space.
- Certifications: Compliant with EN 60204-1, EN 62061, EN ISO 13849-1, VDE 0113-1.
