KL1702, KL1712, KL1722 | 2-channel digital input terminals 120…230 V AC

The KL1702, KL1712, KL1712-0060 and KL1722 digital input terminals acquire the binary control signals from the process level and transmit them, in an electrically isolated form, to the higher-level automation unit. It is possible to connect 60 V DC or 120 V/230 V AC actuators directly. The Bus Terminals contain two channels that indicate their signal state by means of light emitting diodes. The KL1722 version does not have any power contacts. This makes it possible to create individual potential groups. The voltage between input 1 and input 2 must not exceed the max. nominal voltage of 230 V AC.
