Pilz PNOZ S7 750107 Safety Relay 24VDC 4NO 1NC Expansion Unit

Description

The Pilz PNOZ S7 750107 is a premium safety relay contact expansion module engineered by Pilz. Designed to work alongside base safety modules (such as PNOZsigma base units), this expansion relay increases the available number of instantaneous safety contacts without compromising safety ratings.

When an emergency stop button, safety gate switch, or light curtain is triggered, the base relay signals the PNOZ S7 to instantly disconnect power to connected actuators or machinery.

This relay is essential for control panel builders, automation engineers, maintenance leads, and industrial factory operators. In Bangladesh, where industrial compliance, workplace safety, and uninterrupted production lines are top priorities—especially in textile, RMG, packaging, and pharmaceutical sectors—the Pilz PNOZ S7 provides an internationally certified, highly dependable safety switching solution.
