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 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 digital KL2784 Bus Terminal provides four switches that can be used like a relay contact for AC/DC voltages. The electronic switch is realized through high-performance MOSFET transistors with low switch-on resistance.
The switch itself is not short-circuit proof, but due to its high pulse current capability it can cope with current until an external fuse triggers a switch-off.
The outputs are fed via the 24 V power contact in the KL2809. The conductors can be connected without tools in the case of solid wires using a direct plug-in technique.
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 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 KL3011 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 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 job of the KL3052 analog input terminal is to supply power to measuring transducers located in the field and to transmit analog measurement signals with electrical isolation to the automation device.
