analog input terminal allows thermocouples to be connected directly. The Bus Terminal’s circuitry can operate thermocouple sensors using the 2-wire technique.
The KL3351 analog input terminal permits direct connection of a resistor bridge. The bridge voltage, UD, and the supply voltage, UREF, to the bridge are digitized with a 16 bit resolution, and are transmitted along an electrically isolated channel to the supervising automation system.
The KL3356 analog input terminal permits direct connection of a resistor bridge. An improved input circuit makes the KL3356 significantly more accurate than the KL3351.
The KL3361 analog input terminal makes it possible to perform non-central preliminary processing of analog values. It is designed to measure a voltage in the mV range, such as occurs at a strain gauge full bridge.
The analog input terminal KL3404 processes signals in the range between -10 and +10 V. The voltage is digitized to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device.
The analog input terminal KL3408 processes signals in the range between -10 and +10 V. The voltage is digitized to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device.
The KL3444 analog input terminal processes signals in the range between 0 and 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 KL3444 analog input terminal processes signals in the range between 0 and 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 KL3454 analog input terminal processes signals in the range between 4 and 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 KL3458 combines eight channels in one housing and is particularly suitable for space-saving installation in control cabinets. The use of single conductor connection technology enables the connection of multi-channel sensor technology with minimum space requirements.
The analog input terminal KL3464 processes signals in the range between 0 and 10 V. The voltage is digitized to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device.
