NEW 6ES7241-1AH32-0XB0

Model and Series Identification: This module, designated 6ES7241-1AH32-0XB0, is part of the CM 1241 family of communication modules for the SIMATIC S7-1200 system, specifically categorized as an RS232 communication module. It enables serial communication between the S7-1200 CPU and other devices using the RS232 standard.

Core Function: Its primary role is to expand the S7-1200 PLC’s communication capabilities by providing an RS232 interface, facilitating data exchange with RS232-compatible industrial devices such as HMIs, barcode scanners, printers, modems, or other legacy equipment. This supports point-to-point communication in automation systems where RS232 remains a standard interface.

Communication Specifications: The module operates with RS232 protocol, supporting data rates from 300 baud to 115200 baud. It includes standard RS232 signals (TXD, RXD, RTS, CTS, DTR, DSR, DCD, GND) for full handshaking capabilities, ensuring compatibility with a wide range of RS232 devices.

Electrical Characteristics: It draws a maximum current of 120mA from the backplane bus (5V DC). Galvanic isolation (250V AC for 1 minute) is provided between the RS232 interface and the backplane bus, reducing noise interference and protecting the PLC from voltage spikes in industrial environments.

Configuration and Protocols: Configurable via Siemens’ TIA Portal software, allowing users to set communication parameters (baud rate, parity, data bits, stop bits) and select supported protocols. It supports protocols such as PPI (Point-to-Point Interface), Modbus RTU (as master or slave), and USS (Universal Serial Interface), enabling interoperability with various industrial devices.

Mechanical and Protection Features: Housed in a plastic enclosure with an IP20 protection rating, suitable for control cabinet installation. Its dimensions are 45mm (width) x 100mm (height) x 75mm (depth), with a weight of approximately 150g. A front connector is required for wiring the RS232 interface.

Environmental Compliance: Operates in a temperature range of -20°C to 60°C, with storage and transportation temperatures from -40°C to 70°C. It complies with relevant industrial standards (including IEC 61131-2) and RoHS directives, ensuring compatibility with global markets and environmental safety.
