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 KL3012 analog input terminal handles signals in the range from 0 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 KL3112 analog input terminal handles signals in the range from 0 to 20 mA. The current is digitized to a resolution of 16 bits (the default is 15 bits), and is transmitted, in an electrically isolated form, to the higher-level automation device.
The KL3122 analog input terminal handles signals in the range from 4 to 20 mA. The current is digitized to a resolution of 16 bits (the default is 15 bits), and is transmitted, in an electrically isolated form, to the higher-level automation device.
The KL3312 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 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 KL9512 power supply terminal generates an output voltage of 12 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.
