KL1712 | 2-channel digital input terminal 120 V AC/DC
The KL1712 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. It is possible to connect 120 V AC/DC sensors directly. The Bus Terminal contains two channels that indicate their signal state by means of light emitting diodes.
