Two-channel digital input terminal 120/230 V
AC
The KL/KS1722 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 unit. The direct connection of
120 V/230 V sensors is possible. The Bus Terminal has two channels, whose signal state is displayed by
AC
LEDs. The terminal has no power contacts. This makes it possible to create individual potential groups. The
voltage between input 1 and input 2 must not exceed 230 V .
