Siemens 6ES7341-1CH02-0AE0 Communication Processor

SIMATIC S7-300 CP341 Communications Processor 6ES7341-1CH02-0AE0 is a single-interface module that provides RS-422/RS-485 serial communications for the S7-300 PLC, and it ships with a configuration package on CD to set up the link to serial peripherals. It supports a maximum transmission rate of 115.2 kbit/s and can handle serial protocols commonly used with CP341 such as ASCII, RK512, and 3964R for point-to-point connections to devices like printers, modems, or data loggers. The unit is powered from 24 V DC, drawing up to 100 mA from the L+ supply with the backplane 5 V rail supplying up to 70 mA, and it uses the RS422/RS485 interface via a standard X.27 serial connection.
