2.1 Introduction
KL3444: 4-channel analog input terminal 0 ... 20 mA
Fig. 2: KL3444
The EL3444 analog input terminal process signals in the range between 0 and 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.
In the KL3444 Bus Terminal, the four inputs are 2-wire versions and have a common ground potential. This
reference ground of the inputs is electrically isolated from the 0 V power contact. The power contacts are
connected through.
Overload is detected and the terminal status is forwarded to the controller via the K-bus. The Run LEDs
indicate the data exchange with the Bus Coupler, while the Error LEDs indicate overload.
