Description

The Siemens 6ES7341-1AH02-0AE0 is a serial communications module designed for integration into Siemens S7-300 automation systems. It provides a single isolated RS-232C (V.24) interface, enabling reliable serial data exchange between a PLC and external devices such as printers, barcode scanners, HMIs, or third-party industrial equipment. With a 24 V DC supply requirement and optimized power consumption, it ensures stable communication performance in industrial control environments.

The Siemens 6ES7341-1AH02-0AE0 is engineered for flexible serial communication with transmission rates ranging from 0.3 kbit/s to 115.2 kbit/s and a maximum cable length of 15 meters. Its isolated interface design enhances signal integrity and protects the PLC system from electrical interference. Compact construction and robust Siemens engineering make it suitable for continuous industrial operation in demanding automation setups.
