KL1808 - Introduction

Fig.45: KL1808

Bus terminal, 8-channel digital input, 24 V_DC, 3 ms

The KL1808 digital input terminal acquires the binary 24 V_DC control signals from the process level and transmits them, in electrically isolated form, to the higher-level automation device. The bus terminal contains eight channels, consisting of a signal input and 24 V_DC, whose signal states are displayed by light emitting diodes. The power contacts are looped through. With the KL1808, the reference ground for all inputs is the 0 V_DC power contact.
