What it is and where it fits
The 6AG1137-6AA00-2BA0: Rated for 24 V DC with reverse polarity protection, it consumes 0.7 W typical and is isolated to 707 V DC type test. Diagnostics include wire-break detection, diagnostic alarm, and a green/red DIAG LED.
Integration Notes
The 15 mm width allows dense packing on a DIN rail; allow clearance for cable connectors accounting for the 58 mm depth. Configuration of address area (1–247 or extended 1–65535), parity, stop bits, and baud rate is done via the engineering software. 4-wire full duplex and multipoint connections are supported. The module provides RS232 auxiliary signals (RTS, CTS, DTR, DSR, RI, DCD) and a 4 kbyte buffer memory for telegrams.
