Bus terminal, 4-channel digital input, 24 V_DC

The KL1804 and KL1814 digital input terminals acquire the binary 24 V_DC control signals from the process level and transmit them, in an electrically isolated form, to the higher-level automation device. The bus terminals each contain four channels, whose signal states are displayed by LEDs. The power contacts are looped through. For the KL1804 and KL1814 Bus Terminals, the reference ground for all inputs is the 0 V power contact.
