Decentralised periphery interface module

19 September 2012

The new interface module PDP20 F 4 mag, from Pilz, is suitable for series connection of safety switches such as tongue interlocks or magnetic safety switches, up to PL e.

The module provides a standard-compliant solution in accordance with EN ISO 13849-1. It can be connected to dual-channel evaluation devices (such as the PNOZ safety relays, PNOZmulti configurable safety relays, and PSS safety PLCs) and up to four switches can be connected to each module.

The modules also promise a high level of decentralisation with the ability to cascade modules. Each module features four dual-channel inputs and two solid-state safe outputs, one diagnostic solid state output and two test pulsed outputs.

Costing less than a standard safety relay, the interface modules are said to provide a compact and economical solution for series connections, which ultimately find their way back to a final safety relay or other safety controller.
