KL3xxx | Analog input

The KL3012 analog input terminal handles signals in the range from 0В to 20В mA. The current is digitized to a resolution of 12В bits and is transmitted, in an electrically isolated form, to the higher-level automation device. The input channels of the Bus Terminal have differential inputs and possess a common, internal ground potential. An open lead or overload condition are detected, and the terminal status is relayed to the controller via the K-bus. The run LEDs give an indication of the data exchange with the Bus Coupler. The error LEDs indicate an overload condition and a broken wire.

The job of the KL3044 analog input terminal is to transmit analog measurement signals with electrical isolation to the automation device. The input electronics is independent of the supply voltage of the power contacts. The ground connection is the reference potential for the inputs. The error LEDs indicate an overload condition. The KL3044 combines four channels in one housing.

The job of the KL3054 analog input terminal is to transmit analog measurement signals with electrical isolation to the automation device. The input electronics is independent of the supply voltage of the power contacts. The ground connection is the reference potential for the inputs. The error LEDs indicate an overload condition and a broken wire. The KL3054 combines four channels in one housing.

The KL3172 analog input terminal processes signals in the range of 0 to 2В V. The voltage is digitized to a resolution of 16В bits and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the Bus Terminal have differential inputs and a common, internal ground potential. With the high measurement accuracy of В±0.05% (relative to full scale value), the terminal is optimized for high-precision control processes, such as dosing, filling, or quality assurance. The Bus Terminal has two channels within a housing. LEDs indicate data exchange with the Bus Coupler.

The KL3208-0010 analog input terminal enables connection of eight resistance sensors. The Bus Terminal’s circuitry can handle sensors using the 2-wire technique. Linearization over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The Bus Terminal’s standard settings are: resolution 0.01°C within the temperature range of Pt/Ni1000 sensors. The error LEDs indicate sensor faults (e.g. a broken wire).

The KL3228 analog input terminal enables connection of eight resistance sensors. The Bus Terminal’s circuitry can handle sensors using the 1-wire technique. Linearization over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The Bus Terminal’s standard settings are: resolution 0.1°C within the temperature range of Ni1000 sensors. The error LEDs indicate sensor faults (e.g. a broken wire).

The KL3314 analog input terminal allows four thermocouples to be connected directly. The Bus Terminal’s circuitry can operate thermocouple sensors using the 2-wire technique. Linearization over the full temperature range, which can be selected freely, is realized with the aid of a microprocessor. The error LEDs indicate a broken wire. Compensation for the cold junction is made through an internal temperature measurement at the terminals. The KL3314 can also be used for mV measurement.

The KL3403 Bus Terminal enables the measurement of all relevant electrical data of the supply network. The voltage is measured via the direct connection of L1, L2, L3 and N. The current of the three phases L1, L2 and L3 is fed via simple current transformers. All measured currents and voltages are available as root-mean-square values. In the KL3403 version, the effective power and the energy consumption for each phase are calculated. Through the relationship of the root-mean-square values of voltage U * current I and the effective power P, all other information such as the apparent power S or the phase shift angle cos П† can be derived. For each fieldbus, KL3403 provides a comprehensive network analysis and an energy management option.

The KL3454 analog input terminal processes signals in the range between 4В and 20В mA. The current is digitized to a resolution of 12В bits and is transmitted, in an electrically isolated form, to the higher-level automation device. In the KL3454, the four inputs are 2-wire versions and have a common ground potential. The 24В VВ power contact is connected to the terminal, in order to enable the connection of 2-wire sensors without external supply. The power contacts are connected through. The reference ground for all inputs is the 0В V power contact. Overload is detected. The terminal status is relayed to the controller via the K-bus. The run LEDs indicate the data exchange with the Bus Coupler, the error LEDs overload or wire breakage.

The KL3681 Bus Terminal enables measurement of currents and voltages in a wide input range. The measuring ranges are switched automatically, as usual in advanced digital multimeters. For current measurements, two current paths are available, one of which is a high-current path for up to 10 A. The current and the voltage measurement facility can be used for DC and AC. The alternating parameters are output as true RMS values. The measurement readings can be read and processed with commercially available fieldbuses. At the same time, the KL3681 enables the measuring type and range to be set via the bus.
