Siemens 6ES7272-0AA20-0YA0 Operator Interface

Siemens 6ES7272-0AA20-0YA0 is a TD 200 two-line text display (operator interface) designed for S7-200 PLC systems. This LCD backlit module provides two display lines of 20 characters each, with a 5 mm character size, enabling concise prompts and operator messages. The unit dimensions are 148 mm in width and 76 mm in height, and it ships with a 2.5 m cable plus mounting accessories for straightforward installation. It operates on a 24 V DC supply, drawing up to 120 mA, with power supplied either via the S7-200 communications interface or an optional external power source (the CPU sensor power is not loaded). The TD 200 supports ASCII and Cyrillic characters on the 20-character lines, and can accommodate 10 Chinese characters per line. As part of Siemens’ TD 200 text display family, this device is intended to display status information and simple operator messages at the machine level, making it suitable for local monitoring, prompts, and basic human–machine interaction in compact automation setups where space is limited and a dedicated text display is preferred over graphical panels.
