KL3122 | 2-channel analog input terminal 4…20 mA

Описание

The KL3122 analog input terminal handles signals in the range from 4 to 20 mA. The current is digitised to a resolution of 16 bits (the default is 15 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. The KL3122 combines two channels in a 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 give an indication of the data exchange with the Bus Coupler. The error LEDs indicate an overload condition.
