PilzPNOZ Contact Expansion Module, 110 V AC, 4 N/O Safety Contacts plus 1 N/C Auxiliary

Product Description

What this part is

A Pilz PZE 5, part number 474915 — a contact expansion module from the PNOZ X safety relay family, in the 110 V AC version with a 4 N/O plus 1 N/C contact set. Its job is to multiply the number of safety contacts available from a base safety relay: the base unit does the dual-channel monitoring and the PZE follows its enable output, providing four extra positively-driven normally-open safety contacts and one normally-closed auxiliary contact.

Decoding the order code

PZE — Pilz contact expansion module (Kontakterweiterung) within the PNOZ X programme.

5 — five contacts in total on the module.

4S1Ö / 4 N/O 1 N/C — four normally-open safety contacts and one normally-closed auxiliary contact.

474915 — Pilz part number for the 110 V AC version.

100897 — the additional number carried on this unit’s label.

What these specs mean in practice

The module runs on a 110 V AC supply; the same PZE 5 exists at 24 V DC (474910) and other voltages. The extra contacts follow the enable output of a PNOZ base unit, so the achievable performance level is set by the whole chain of base relay, wiring and feedback loop.

Quantity and configuration

Sold as one module, supplied as the module alone.

Interchange guidance

PZE 5, PZE5 and part number 474915 are the same module at 110 V AC. PZE 5 474910 is the 24 V DC version. PZE 9 (for example 774150, 8 N/O 1 N/C) is a larger expander with a different contact count. A PNOZ base unit is a different class of device from an expander.
