The KL2022 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation. It handles different load currents, and its outputs are protected against short-circuit. The Bus Terminal contains two channels that indicate their signal state by means of light emitting diodes.
The KL2032 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation.
The KL2124 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation.
The KL2212 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation.
The KL2488 (ground switching) digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation.
The KL3001 analog input terminal handles signals in the range from -10 to +10 V. The voltage is digitized to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device.
The KL3002 analog input terminal handles signals in the range from -10 to +10 V. The voltage is digitized to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device.
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.
