Product details

RS-232 serial communication for S7-1500

The 6AG1540-1AD00-7AA0: It's designed for extended temperature range: horizontal installation from -40 to 70 °C; vertical up to 40 °C. 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.
