Startup from -25 °C. This makes it suitable for harsh environments. The module draws 35 mA from the backplane bus and dissipates 0.6 W typical. It has a 2 kbyte buffer for telegrams, supports fast startup, and provides diagnostic alarms plus wire-break detection. Mounts on the S7-1500 mounting rail. Width is 35 mm. Powered from the backplane bus. The RS-232 port is on the front, with green/yellow LEDs for TxD, RxD, and RUN.","metaTitle":"Siemens 6AG1540-1AD00-7AA0 SIPLUS S7-1500 CP RS-232, -40..70","metaDescription":"SIPLUS CP 1540-1 RS-232 module for S7-1500, -40 to 70 °C, 19.2 kbit/s.
