Product Description:
The Beckhoff KL3448 from KL Analog Input Modules is built for use in high-demand applications.
This unit contains eight analog input channels in one small package, which suits applications that need to monitor many current signals in restricted control cabinet areas. The module represents Beckhoff's method for building efficient hardware solutions that retain excellent execution results. A standard signal current in the range of 0 to 20 mA can be processed by each of the eight inputs while the internal resistance of the system stays below 85 ohms. The measurement system enables accurate sensor and actuator signal reading through its design that reduces input voltage drop. This module guarantees protection for signals measuring ±10 V common-mode voltage to increase operational stability when processing signals in noisy electrical conditions. Each analog input measurements occur within a 4-millisecond conversion period using 12-bit resolution to support dependable real-time signal processing functions for control and monitoring operations. The measurement accuracy reaches ±0.3% precision concerning the full-scale value.
The module includes surge voltage protection that raises its durability while preventing unfavorable overvoltage events through its 30 V DC capacity. Processing power for the KL3448 module originates from the Beckhoff K-bus, which delivers 20 mA through its power contacts to enhance terminal block system operational efficiency. The module creates an 8 x 16-bit data entry interface into the process image, together with optional 8 x 8-bit control/status entries, which simplifies integration with Beckhoff's TwinCAT automation software. Users can configure the module through the TwinCAT System Manager interface. The input module functions optimally within a -25°C to +60°C temperature range and provides compatibility with standard DIN rail (EN 60715). It can be purchased at Wake Industrial with a one-year warranty.
