<div class=ident><h1>PNOZ mi1p</h1><span class=mfr>Pilz GmbH & Co. KG</span><span class=badge>SAFETY INPUT MODULE</span></div>
<p class=oneline>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.</p>
<div class=metarow><span class=m>Order no. <b>773400</b></span><span class=m>Coated <b>773405</b></span><span class=m>Inputs <b>8 (I0 to I7)</b></span><span class=m>Size <b>22.5 x 94 x 121 mm</b></span><span class=m>Mounting <b>TS35 rail</b></span><span class=m>Terminals <b>X1 + X2, 5 each</b></span></div>

It installs with the whole library from the <a href="https://wiki.adom.inc/john/wolfgang-kicad-library">Wolfgang's KiCad library (KiCad PCM repository)</a>, where this footprint and 3D model are linked to it.</div>
<div class=callout style="border-left-color:#d29922;background:rgba(210,153,34,.09);border-color:rgba(210,153,34,.3)"><b>Datasheet-built CAD: check before you rely on it.</b> 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.</div>
<div class=callout><b>End of life.</b> 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.</div>

<div class=callout>In the upstream <code>devices.kicad_sym</code> 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.</div>

<ul class=ul>
<li><b>Every number on this page</b> 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).</li>
<li><b>Symbol:</b> <code>PILZ_PNOZ_mi1p</code> from <a href="https://github.com/realAscot/kicad-symlib">realAscot/kicad-symlib</a> by Adam Skotarczak, via the fork <a href="https://github.com/johnAdom/kicad-symlib">johnAdom/kicad-symlib</a> at <code>bb8619a</code>, where its Footprint field was set and its pins renumbered by terminal.</li>
<li><b>Footprint:</b> 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.</li>
<li><b>3D model:</b> modelled in CadQuery to the published envelope and front view (details representative); the part number was laser-etched with the <code>adom-chip-laser</code> 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.</li>
<li><b>Fusion .lbr:</b> generated by <code>adom-lbr</code> and validated; not hand-checked in Fusion.</li>
