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 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.
The KL3022 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.
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.
The KL4002 analog output terminal generates signals in the range from 0 to 10 V. The voltage is supplied to the process level with a resolution of 12 bits and is electrically isolated.
The KL4021 analog output terminal generates analog output signals in the range from 4 to 20 mA. The power is supplied to the process level with a resolution of 12 bits and is electrically isolated.
The KL4022 analog output terminal generates analog output signals in the range from 4 to 20 mA. The power is supplied to the process level with a resolution of 12 bits and is electrically isolated.
The KL6021 serial interface allows devices with an RS422 or RS485 interface to be connected. The device connected to the terminal communicates with the automation device via the Bus Coupler.
