Pilz PNOZ s7.1 750167 24V DC Cascading Contact Expansion Module in Delhi

Check the Exact 750167 Model Before Ordering

PNOZ s7.1 (750167) is the screw-terminal version. PNOZ s7.1 C (751167) is a separate spring-loaded-terminal version. Both are described as 24 V DC, three-N/O cascadable contact expansion products, but the connection method and part number differ. Choose the version specified in the electrical drawing or bill of materials rather than treating the two codes as identical.
This unit expands contacts for a supported safety-related control arrangement. It is not a standalone safety controller and must not be selected only because it is labelled a safety relay. A qualified machine-safety or controls professional should confirm the base-unit compatibility, interface, feedback monitoring, contact utilisation and overall safety design against current Pilz documentation.

Product Specifications

How Cascading Contact Expansion Helps

The PNOZ s7.1 is intended to increase the available safety contacts within a compatible monitored safety system. Its cascade-capable design provides a connection arrangement to support further expansion modules where the manufacturer's permitted architecture and power budget allow it. This can be useful in planned equipment modifications when additional monitored contact outputs are required, but a contact expansion does not create an independent safety function by itself.
The three N/O contacts are an essential purchasing specification. The 24 V DC supply is separate from the switching ratings of the relay contacts. Do not assume that the supply voltage describes every permitted contact load. Validate the relevant utilisation category, load conditions, required protective devices and installation limits in the official operating instructions before commissioning.

Typical Procurement and Engineering Scenarios

This model can be considered during safety-related contact expansion for machinery and production equipment such as packaging lines, conveyors, guarded workcells and automated assembly systems, where the documented system design explicitly permits it. The use case is not enough to establish compatibility or a safety performance level: that determination belongs to the overall machine risk assessment and validated safety design.
For an exact replacement, compare the installed module's label, part number, terminal style, connected base unit and panel configuration. Do not substitute a different PNOZ s7 or s7.2 product based solely on similar dimensions or supply voltage.

Ordering Pilz PNOZ s7.1 750167 for Delhi

Before checkout, verify the exact manufacturer code 750167, the seller's order unit, current price and GST, physical availability and serviceability for your Delhi delivery pincode. If work is scheduled around the part, obtain a dispatch and lead-time confirmation from the supplier; displayed availability or estimates may change.
For institutional purchases, provide the part number, required quantity, destination pincode, company GST details and any documentation or purchase-order requirements. Ask the supplier to confirm the supplied terminal version and product condition. Installation, testing and safety validation should be handled by competent personnel using the official Pilz instructions.

Frequently Asked Questions

1. What is the exact Pilz part number for PNOZ s7.1 24 V DC 3 N/O?

The screw-terminal, cascadable PNOZ s7.1 module is 750167. This exact number should appear on procurement documentation and the supplied product label.

2. Is PNOZ s7.1 750167 a standalone safety relay?

No. It is a contact-expansion module used within an appropriate monitored safety control arrangement. It does not independently replace the base safety controller or the required safety-system design.

3. How many normally open safety contacts does the module provide?

The Pilz product listing confirms three normally open safety contacts (3 N/O). Do not infer an additional auxiliary contact from conflicting reseller descriptions without checking the exact approved technical documentation.

4. What is the operating supply voltage?

It requires 24 V DC supply. The 24 V DC supply and the permissible contact-switching ratings are different specifications.

5. What is the difference between 750167 and 751167?

750167 uses plug-in screw terminals. 751167, identified as PNOZ s7.1 C, uses spring-loaded terminals. Verify the terminal style and approved system configuration before substituting either version.

6. What is meant by cascading on this module?

Cascading refers to the capability to connect further compatible contact-expansion modules according to Pilz's approved architecture, connection and power requirements. It does not mean unlimited modules may be added.

7. What are the module dimensions?

The Pilz product page specifies 98 mm height, 17.5 mm width and 120 mm depth. Check panel clearance and installation details in the applicable manual.

8. Does this product guarantee a particular machine safety level?

No. Any required category, PL or SIL depends on the complete safety circuit, the compatible base device, diagnostic provisions, installation and validation. The product alone does not establish the achieved level.

9. Is the module available for delivery in Delhi?

Review the live Indus MegaMart listing with your Delhi pincode. Confirm current inventory, GST, shipping and dispatch requirements with the supplier before placing a time-sensitive order.

10. What should a maintenance buyer verify for replacement procurement?

Match 750167, 24 V DC, 3 N/O, screw terminals, the application wiring and the compatible base-unit system. Request any required traceability and product documentation from the supplier.
