PNOZ S7.1 Pilz 24VDC PILZ 750167 CONTACT EXPANSION 3 N/O 1 N/C 24VDC

It looks like you’re referring to a Pilz safety relay module, specifically the PNOZ S7.1 (750167). This module is designed for safety-related applications and is used to monitor safety functions such as emergency stops, safety gates, light barriers, and so on.

The information you provided likely means:

PNOZ S7.1: This is the model number of the Pilz safety relay module.
24VDC: This indicates the operating voltage of the module, which is 24 volts DC (Direct Current).
750167: This is the specific part number or identification number for the PNOZ S7.1
CONTACT EXPANSION 3 N/O 1 N/C: This part of the information refers to the available contact configurations.
3 N/O (Normally Open) contacts: These are three normally open contacts that close (become conductive) when the safety relay is activated (safe condition)
1 N/C (Normally Closed) contact: This is one normally closed contact that opens (becomes non-conductive) when the safety relay is activated (safe condition).

In summary, the Pilz PNOZ S7.1 (750167) safety relay module operates at 24VDC and provides three normally open (N/O) contacts and one normally closed (N/C) contact for integrating safety functions into machinery and equipment.
