The Keba AR281 is a high-performance analog input/output module designed for the KeConnect C5 series of control systems. This versatile module is engineered for precision and reliability in demanding industrial automation environments. It features four high-resolution analog inputs capable of processing various signal types, including voltage (±10 V), current (0/4-20 mA), and direct temperature measurements from Pt100, Pt1000, and Ni1000 sensors. Additionally, it provides two analog outputs, making it an ideal solution for applications requiring accurate data acquisition and control of analog actuators. Its compact design and integration into the EtherCAT bus system ensure fast communication and easy installation.
