Beckhoff KL3012 Bus Terminal 2-channel analog input

Beckhoff KL3012 Bus Terminal 2-channel analog input

The KL3012 analog input terminal handles signals in the range from 0 to 20 mA. The current is digitized to a resolution of 12 bits and is transmitted, in an electrically isolated form, to the higher-level automation device. The input channels of the Bus Terminal have differential inputs and possess a common, internal ground potential. An open lead or overload condition are detected, and the terminal status is relayed to the controller via the K-bus. The run LEDs give an indication of the data exchange with the Bus Coupler. The error LEDs indicate an overload condition and a broken wire.
