analog input terminal allows thermocouples to be connected directly. The Bus Terminal’s circuitry can operate thermocouple sensors using the 2-wire technique.
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.
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 bidirectional KL5051 SSI interface terminal is used to connect digital servo drives. The interface consists of two logical channels. The first channel is used to position the drive
The KL5121 Bus Terminal can be used to implement a linear path control. The terminal reads an incremental signal, which can be supplied by an incremental encoder or a pulse generator, and switches the outputs when the counter reaches a previously defined state.
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.
The KL6051 serial interface terminal makes it possible to exchange data between different fieldbus systems. Full duplex data exchange is possible, independently of the higher-level fieldbus. Under the terminal’s default setting, 32 inputs and 32 outputs are transferred between the fieldbus systems.
The KL9050 coupler terminal replaces the Bus Coupler on a Bus Terminal block. The KL9050 is the counterpart to the KL9020. The S(F)TP cable (shielded twisted pair) is plugged into the upper socket, providing the logical connection to the Bus Coupler.
The KL9210 power feed terminal makes it possible to set up various potential groups with the standard voltage of 24 V DC. In order to monitor the supply voltage, the terminal with diagnostics reports the status of the power feed terminal to the Bus Coupler through two input bits. It is thus possible for the controller to check the distributed peripheral voltage over the fieldbus.
The KL9505 power supply terminal generates an output voltage of 5 V DC from the (24 V DC) input voltage, which can be accessed at the terminal. The following Bus Terminals are also supplied with this voltage via the power contacts. The power LEDs indicate the terminal’s operating state. The input voltage and the output voltage U0 are not electrically isolated.
