Beckhoff KL3054 Analog Input Terminal
The job of the Beckhoff KL3054 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 and a broken wire. The KL3054 combines four channels in one housing.
