The KL2134 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation.
The KL2184 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 KL2521 output terminal alters the frequency of a binary signal and (electrically isolated from the K-bus) outputs it. The frequency is preset by a 16 bit value from the automation unit.
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 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 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 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.
This module can be used to determine paths and to calculate speeds at the same time. The ultrasonic transducer rods are connected directly to the RS422 interface.
The module is equipped with 2 outputs for 3-wire connections. It is designed for X20 6-pin terminal blocks. If needed (e.g. for logistical reasons), the 12-pin terminal block can also be used.
