The new interface module PDP20 F 4 mag is ideal for series connection of safety switches, such as tongue interlocks or magnetic safety switches, up to PL e.  As such, it provides a standard-compliant solution in accordance with EN ISO 13849-1.

The interface module can be connected to dual-channel evaluation devices (such as the popular PNOZ safety relays, PNOZmulti configurable safety relays, PSS safety PLCs).  Up to 4 switches can be connected to each PDP20 module.  PDP20 interface modules also offer a high level of decentralisation due to the ability to cascade modules.

Each module features 4 dual-channel inputs and 2 solid-state safe outputs (OSSDs), 1 diagnostic solid state output and 2 test pulsed outputs.  To cascade multiple PDP20 modules, the OSSDs of one are fed into one of one of the dual-
