PNOZ mi1p

Pilz GmbH & Co. KGSAFETY INPUT MODULE

Expansion module for the configurable PNOZmulti safety system that adds 8 safety inputs, I0 to I7, for E-STOP pushbuttons, safety gates, light beam devices, two-hand buttons, enabling switches and operating mode selectors. It takes its 5 V supply from the PNOZmulti base unit, up to 8 can hang off one base unit, and it snaps onto a 35 mm top-hat rail at 22.5 mm wide.

Schematic symbol by Adam Skotarczak. The symbol is PILZ_PNOZ_mi1p from his realAscot/kicad-symlib, © 2025 Adam Skotarczak, ionivation.com, free to use, modify and redistribute with credit. It installs with the whole library from the Wolfgang's KiCad library (KiCad PCM repository), where this footprint and 3D model are linked to it.

Datasheet-built CAD: check before you rely on it. The 3D model is built from Pilz's published dimensions and front view, not from Pilz's own CAD, so its envelope is right but details are representative. The footprint's terminal positions and pitch are scaled from the front-view drawing and are approximate (plan for about 0.5 mm). Fine for cabinet layout and documentation; compare against the Pilz drawing before anything depends on exact positions.

End of life. Pilz lists the 773400 as at the end of its product lifecycle. Check with the manufacturer for a successor before designing it into a new cabinet.

Symbol & footprint

Schematic symbol by Adam Skotarczak

DIN-rail panel footprint (terminal positions approximate), front face on the TS35 rail

A cabinet panel-layout footprint, not a PCB land pattern: the outline is the 22.5 W x 94 H x 121 front face, the origin is the rail centre line, and the pads sit at the terminal positions so symbol pins and 3D terminals line up.

Pin map

In the upstream devices.kicad_sym this symbol's pin numbers repeated or were empty, so KiCad could not map them to pads. The fork numbers them by terminal position (X1.1 to X2.5) and keeps the manufacturer labels as pin names.

Provenance

Every number on this page is from the manufacturer document in the Datasheet section: Pilz operating manual 20880-EN-07: features and front view (2.2, 2.3), dimensions (5.2), technical details and safety data (8, 8.1), order references (9).
Symbol: PILZ_PNOZ_mi1p from realAscot/kicad-symlib by Adam Skotarczak, via the fork johnAdom/kicad-symlib at bb8619a, where its Footprint field was set and its pins renumbered by terminal.
Footprint: drawn from the front view and dimension drawing. Outline and rail position follow the drawing; terminal positions and pitch are scaled from the front view and are approximate.
3D model: modelled in CadQuery to the published envelope and front view (details representative); the part number was laser-etched with the adom-chip-laser service and inlaid on the front. The manufacturer's own CAD download was not reachable from here (Pilz's site refused automated access), so this model is datasheet-built.
Fusion .lbr: generated by adom-lbr and validated; not hand-checked in Fusion.
