Typically the new e-marked PNOZ X2C and PNOZ X2.1C relays will be used to monitor emergency stop switches, guard switches and limit switches on dustbin lorries, road sweepers, mobile access platforms (cherry pickers), vehicle-mounted hoists and similar applications.
Broadly similar to the existing PNOZ X2 and X2.1 safety relays, the new models feature two normally-open safety contact outputs and are suitable for use in applications meeting the requirements of EN 954-1 Category 2 or 4.
While the PNOZ X2C has a monitored manual reset, the PNOZ X2.1C can be configured by the customer to have either a manual reset or an automatic reset, depending on the requirements of the application.
To assist with commissioning and troubleshooting, both relays have LEDs on the front to indicate the status of the outputs and the presence of the 24V AC/DC control supply.
Type approval e-marking in accordance with Directive 72/245/EEC, Radio interference (electromagnetic compatibility) of vehicles (as last amended by Directive 95/54/EC, Automotive Electromagnetic Compatibility) permits the new relays to be used on vehicles or incorporated within aftermarket vehicle accessories supplied in the EU. The Pilz PNOZ X2C and X2.1C safety relays were tested by Elmac GmbH and the EC Type Approval Certificate was issued by Kraftfahrt-Bundesamt.
