The Beckhoff KL3454 is an industrial module with an analog input, 12-bit resolution, and a temperature range of -25°C to +60°C. It provides two analog inputs with 8 mA excitation current and can be used for current, voltage, resistance, temperature, and bridge sensor measurements. It is designed with protection against high voltages, transients, and shorts to ground, and is certified for RoHS compliance. It has an integrated differential preamplifier for low-noise, low-temperature drift operation, and supports various input ranges and filtering settings to ensure accuracy and precision. It supports an extended temperature range of -40°C to +85°C, making it suitable for applications in harsh industrial environments.
