Convenient speed monitoring – PNOZ s30

As the new Machinery Directive becomes valid, a new requirement in the field of drive monitoring comes to the fore: When the drive is brought to a standstill, the operating status must be safely monitored and maintained.

This requirement is met by the . It provides safe monitoring of standstill, speed and direction of rotation. So the right speed monitoring solution is available for each application.

Contact expansion module PNOZ s22 – Twice as good

PNOZ s22 provides two relay functions that can be controlled separately in accordance with PL e of EN ISO 13849-1. Each relay function provides 3 N/O/1 N/C contacts. These can be controlled separately, so that the outputs can be assigned different functions, depending on the base unit. Safe separation between the two relay functions enables different potentials to be switched. Multiplication of the relay contacts permits an extended range of functions for applications; this is an interesting feature, especially in connection with the safe speed monitor PNOZ s30.

Safety relay PNOZ s4 with approval in accordance with EN 81-1/A3

The "Lifts standard” EN 81-1 defines the safety rules for the "Construction and installation of lifts; Part 1: Electric lifts". The PNOZ s4 has this approval and guarantees lift operators and lift manufacturers maximum functionality in minimum width. With an installed width of 22.5 mm, the PNOZ s4 achieves PL e in accordance with EN ISO 13849-1 and SIL CL claim limit 3 in accordance with EN IEC 62061. The applications of the PNOZ s4 range from passenger lifts and load and goods elevators to all kinds of lifting equipment that are subject to this standard.

Safe firing with PNOZ s4.1

Thanks to three safe, diverse safety contacts, the PNOZ s4.1 is approved for use in burner controls. It is approved in accordance with the standard EN 50156-1 for electrical equipment on furnaces, in particular with regard to the requirements for application design and installation.

Multiple expansion – Contact expansion modules PNOZ s7.1 and PNOZ s7.2

With a base unit and a PNOZ s7.1, the number of safety contacts can be expanded almost without limit. Up to ten PNOZ s7.2 can be connected to a PNOZ s7.1. If you need more contacts, an additional PNOZ s7.1 can be added to the series. No wiring is involved – just a connector and one simple hand movement. At just 17.5 mm wide, the PNOZ s7.1 has three safety contacts, while the PNOZ s7.2 has four safety contacts plus one auxiliary contact. They can be combined with other PNOZsigma expansion units at any time.

Contact expansion module PNOZ s20 with semiconductor outputs

The number of semiconductor outputs can be expanded in conjunction with a base unit, such as the PNOZ s3 for example: If max. ten semiconductor outputs are needed, the contact expansion module PNOZ s20 can be connected directly to a base unit. If more safe semiconductor outputs are needed, the contact expansion module PNOZ s7.1 can be integrated in between. The number of semiconductor outputs can thus be increased almost infinitely.
