    The ELX3202 analog input terminal allows the direct connection of RTDs located in hazardous areas classified Zone 0/20 or 1/21. The circuitry of the ELX3202 can operate sensors with 2, 3 and 4-wire technology. Linearization is carried out over the entire freely selectable temperature range. By default the terminal is set to PT100 sensors with 2-wire technology.

  • Page 30: Basic Function Principles

    For analog I/O devices from Beckhoff the rule is that the limit with the largest value is chosen as the full scale value of the respective product (also called the reference value) and is given a positive sign. This applies to both symmetrical and asymmetrical measuring spans.

  • Page 31: Temperature Coefficient Tk [Ppm/K]

    A manufacturer can alleviate this by using components of a higher quality or by software means. The temperature coefficient, when indicated, specified by Beckhoff allows the user to calculate the expected measuring error outside the basic accuracy at 23 °C.

  • Page 32: Single-Ended/Differential Typification

    • The term "electrical isolation" should be clarified in advance. Beckhoff IO modules feature 1..8 or more analog channels; with regard to the channel connection a distinction is made in terms of: ◦ how the channels WITHIN a module relate to each other, or ◦...
  • Page 33 The property of electrical isolation indicates whether the channels are directly connected to each other. ◦ Beckhoff terminals/ boxes (and related product groups) always feature electrical isolation between the field/analog side and the bus/EtherCAT side. In other words, if two analog terminals/ boxes are not connected via the power contacts (cable), the modules are effectively electrically isolated.

  • Page 36: Temporal Aspects Of Analog/Digital Conversion

    The conversion of the constant electrical input signal to a value-discrete digital and machine-readable form takes place in the analog Beckhoff EL/KL/EP input modules with ADC (analog digital converter). Although different ADC technologies are in use, from a user perspective they all have a common characteristic: after the conversion a certain digital value is available in the controller for further processing.
