Product Name: BECKHOFF KL1889 HD Bus Terminal, 16-Channel Digital Input
Product Brand: BECKHOFF
Product Code: KL1889
Product Artikel: BECKHOFF KL1889 HD Bus Terminal, 16-Channel Digital Input
The KL1889 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 16 channels, whose signal states are displayed by LEDs. The terminal is particularly suitable for space-saving use in control cabinets. By using the single-conductor connection technique, a multi-channel sensor can be connected in the smallest space with a minimum amount of wiring. The power contacts are looped through. The KL1889 Bus Terminal takes the 24 V power contact as its reference for all inputs. The conductors 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.
