The Siemens 6ES7272-0AA30-0YA1 is a SIMATIC S7 TD 200 text display configured as a spare part for the S7-200 platform, with a PPI interface and a 2-line LCD rated for -40 to 70 °C ambient operation. IP65 at the front lets it mount in panels exposed to washdown or splashes. Power comes via the S7-200 communications cable or an optional external 24 V DC supply — the CPU's sensor supply isn't loaded by this unit.
Integration notes
Panel cutout is 138 mm wide by 68 mm high; overall depth behind the panel is 27 mm, so it fits tight enclosures. The included 2.5 m cable connects directly to the S7-200 CPU's PPI port. Up to 126 nodes on the PPI network, max 187.5 kbit/s. 9 configurable system keys and 20 ASCII characters per line (10 for Chinese). No AS-Interface support, no alphanumeric keyboard — it's a pure text display.
