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.
he KL3142 analog input terminal handles signals in the range between 0 and 20 mA. The current is digitized to a resolution of 16 bits, and is transmitted, in an electrically isolated form, to the higher-level automation device.
The KL3152 analog input terminal handles signals in the range between 4 and 20 mA. The current is digitized to a resolution of 16 bits, and is transmitted, in an electrically isolated form, to the higher-level automation device.
The KL3162 analog input terminal processes signals in the range of 0 to +10 V. The voltage is digitized to a resolution of 16 bits and is transmitted, electrically isolated, to the higher-level automation device.
The KL3182 analog input terminal processes signals in the range of -2 to +2 V. The voltage is digitized to a resolution of 16 bits and is transmitted, electrically isolated, to the higher-level automation device.
The KL3201 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.
