Beckhoff KL3044 Bus Terminal 2-channel analog input

Beckhoff KL3044 Bus Terminal 2-channel analog input

The job of the KL3044 analog input terminal is to transmit analog measurement signals with electrical isolation to the automation device. 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 combines four channels in one housing.
