Product Description

The Siemens CP340 module (6ES7340-1AH02-0AE0) is a serial communication module for SIMATIC S7-300 systems, offering a single SIMATIC RS-485 interface for point-to-point data exchange. It supports protocols like ASCII and 3964(R), enabling integration with sensors, PLCs, or peripherals. Operating at 24V DC within 0–60°C, it suits industrial environments such as manufacturing and process automation. The module lacks physical I/O but facilitates reliable long-distance communication up to 1200 meters via its robust RS-485 interface. Compact and DIN-rail-mountable, it ensures minimal space usage. While it excels in legacy serial connectivity, it lacks modern interfaces like Ethernet. No battery or display is included, focusing solely on stable data transmission in harsh conditions.
