Introduction

KL3444: 4-channel analog input terminal 0 ... 20 mA

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.

KL3454: 4-channel analog input terminal 4 ... 20 mA

The EL3454 analog input terminal process signals in the range between 4 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 KL3454 Bus Terminal, the four inputs are 2-wire versions and have a common ground potential. This reference ground of the inputs is connected to the 0 V power contact. The 24 V power contact is connected to the terminals, in order to enable the connection of 2-wire sensors without external supply. 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.
