Product Name: BECKHOFF KL1804 HD Bus Terminal, 4-Channel Digital Input
Product Brand: BECKHOFF
Product Code: KL1804
Product Artikel: BECKHOFF KL1804 HD Bus Terminal, 4-Channel Digital Input
The KL1804 digital input terminal acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation device. The Bus Terminal contains four channels, consisting of a signal input, 24 V DC and 0 V. The signal states are displayed by LEDs. The power contacts are looped through. The reference ground for all inputs is the 0 V power contact. The wires can be connected without tools in the case of solid wires using a direct plug-in technique. The HD Bus Terminals (High Density) with increased packing density feature 16 connection points in the housing of a 12 mm terminal block.
