The KL1124 digital input terminal acquires the binary 5 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains four channels that indicate its signal state by means of light emitting diodes. The 5 V supply voltage can be generated with the power supply terminal and fed into the power contacts.
The KL1302 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal has two channels, whose signal state is displayed by light emitting diodes.
The KL1402 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains two channels that indicate its signal state by means of light emitting diodes.
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 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 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 KL2502 output terminal modulates the pulse width of a binary 24 V DC signal and outputs it electrically isolated from the K-bus. The mark/space ratio is prescribed by a 16 bit value from the 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 KL3021 analog input terminal handles signals in the range from 4 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.
