The KL3152 analog input terminal handles signals in the range between 4 and 20 mA. The current is digitized to a resolution of 16 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 a common, internal ground potential. With its high measurement accuracy of ±0.05% (relative to full scale value), the terminal is optimized for high-precision control processes, such as dosing, filling, or quality assurance. The KL3152 combines two channels in a single housing. An open lead or overload condition are detected, and the terminal status is relayed to the controller via the K-bus. The run LEDs indicate data exchange with the Bus Coupler, the error LEDs indicate overload.
