Digital Inputs connected to 0VDC
The KL1488 digital input terminal acquires the binary 24 VDC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The bus terminal contains eight channels, whose signal states are indicated by light emitting diodes. The KL1488 has the 24 VDC power contact as the reference point for all inputs. The power contacts are connected through.
