Product Description:

The Beckhoff KL6211 is an intelligent analog input module for use with AS-Interface (Actuator Sensor Interface) networks. The KL Analog Input Modules series is a part of the KL Analog Input Modules series, which has been engineered to make it easy to integrate AS-i slave devices into modular control architectures which makes it a good fit for decentralized automation environments. The KL6211 has been designed as a single channel communication device, which supports both AS-Interface protocol versions 2.0 and 2.1 and therefore is compatible with many devices. The module can support up to 31 slaves in version 2.0 and up to 62 slaves (digital and analog) in version 2.1. The adaptability of the KL6211 allows it to deal with complex automation settings without the need for additional interfaces.

One thing that sets this module apart are its diagnostic capabilities, it continually looks for power failures, slave malfunctions, and parameterization errors. The built in diagnostics enable quick fault detection and aid with proactive maintenance, lowering downtime and increasing system reliability. The use of a two line connection system using Beckhoff's reliable spring force technology makes installation user friendly. The AS i network is flexible when it comes to address assignment, and so it can be done automatically or manually through configuration, making it easy to set up and scale. The KL6211 can be integrated seamlessly into the Beckhoff I/O system and communicates with the K-bus with a typical current consumption of 55 mA, drawing an additional 60 mA (plus load) via power contacts.

Depending on the application, data handling and interfacing of parameters are optimized with selectable bit widths in the process image (12, 22, or 38 bytes). The KL6211 has an operating temperature range of 0 to 55C and is suitable for standard industrial cabinet installations with IP20 protection rating. This product weighs approximately 55 grams, provides robust communication performance, built in diagnostics and high flexibility in a compact DIN rail-mountable format ideal for scalable and reliable AS-i automation networks.
