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 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 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 KL3202 analog input terminal allows resistance sensors to be connected directly. The Bus Terminal’s circuitry can operate the sensors using 2-wire or 3-wire connection techniques. Linearization over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely.
