KL/KS3041, KL/KS3051 - Introduction

The job of the KL/KS3041 and KL/KS3051 analog input terminals is to supply power to measuring transducers located in the field, and to transmit analog measurement signals with electrical isolation to the automation device.
KL/KS3041 process signals in the range from 0 mA to 20 mA.
KL/KS3051 process signals in the range from 4 mA to 20 mA.
The voltage for the sensors is supplied to the terminals via the power contacts. The power contacts can optionally be supplied with operating voltage in the standard way or via a power feed terminal (KL9xxx) with electrical isolation. The input electronics is independent of the supply voltage of the power contacts. The 0 V rail is the reference potential for the inputs. The Run LEDs indicate the exchange of data with the Bus Coupler, while the Error LEDs indicate overload and wire breakage.
