Beckhoff KL3464 4-Channel Analog Input Terminal

The Beckhoff KL3464 is a 4-channel analog input Bus Terminal designed to process standardized 0 to 10 V DC voltage signals from industrial field devices. Operating with 12-bit resolution, this compact 12 mm I/O module digitizes analog process signals—such as pressure sensors, position transducers, temperature transmitters, and potentiometer outputs—and transfers them with electrical isolation to the higher-level automation system.
