KL6041 - Introduction

KL6041 - Introduction 1:
KL6041

The KL6041 serial interface enables the connection of devices with an RS422 or RS485 interface. The device connected to the KL6041 terminal communicates with the automation device via the Bus Coupler. The active communication channel operates independently of the higher-level bus system in full or half duplex mode at up to 115.2 kbit/s. The differential signal transmission according to RS422 guarantees high immunity to interference through electrically isolated signals.
