KL304x, KL305x - Single-, Dual- and Four-Channel Analog Input Terminals 0 to 20 mA and 4 to 20 mA, Single ended

KL3044, KL3054 – Introduction

KL3044, KL3054

The job of the KL3044 and KL3054 analog input terminals is to transmit analog measurement signals with electrical isolation to the automation device.
The KL3044 terminal processes signals in the range from 0 mA to 20 mA.
The KL3054 terminal processes signals in the range from 4 mA to 20 mA. The input electronics is independent of the supply voltage of the power contacts. The ground connection is the reference potential for the inputs. The error LEDs indicate an overload condition. The KL3044 and KL3054 combine four channels in a single housing.
