The KL2012 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation.
The KL3012 analog input terminal handles signals in the range from 0 to 20 mA. The current is digitized to a resolution of 12 bits and is transmitted, in an electrically isolated form, to the higher-level automation device.
The KL4012 analog output terminal generates analog output signals in the range from 0 to 20 mA. The power is supplied to the process level with a resolution of 12 bits and is electrically isolated.
