KL1809 - Introduction

Fig.47: KL1809

Bus terminal, 16-channel digital input, 24 V_DC, 3 ms

The KL1809 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 sixteen channels whose signal states are indicated by light emitting diodes. The power contacts are looped through. With the KL1809, the reference ground for all inputs is the 0 V_DC power contact.
