The 6ES7193-4CK20-0AA0: The narrower sibling, 6ES7193-4CC30-0AA0, shares the same depth (43 mm) and height (132 mm) but cuts the width to 15 mm. That halves the DIN-rail footprint and reduces the terminal count. The 4CK20 is the one you want when the PROFIsafe power module needs the full 2x3+2x4 screw-terminal array and AUX1 bus access — the 4CC30 cannot deliver those connections in the same panel cutout.
At 30 mm wide, 132 mm tall, and 43 mm deep, this module occupies one standard ET200S slot on a DIN rail after the power module. The screw terminals face outward, and the AUX1 interrupt means you must plan the daisy-chain jumper accordingly for safety isolation. A 116 g part — nothing special for panel handling.
Lifecycle stage is marked 'current' — Siemens still builds it, no last-time-buy window. Genuine is genuine, same part different passport if it crosses a border. We source it to quote against an RFQ; let me be transparent that the delivery quantity is one piece, so for larger BOM volumes we'll confirm lead time per batch.
