Beckhoff EL3204-0200
EL3204-0200 | 4-channel universal input terminal for RTD up to 240 kΩ, NTC 20 k, 16 bit
Descripción
The analog EL3204-0200 input terminal enables direct connection of four resistance sensors up to 240 kΩ, so that the usable measuring range is significantly larger compared with the EL3204. The EtherCAT Terminal circuit can operate sensors using the 2-wire technique. The resistance values are converted (linearisation) in the terminal either based on preset characteristic curves, conversion formulas with specific material parameters (e.g. according to IEC 60751, Steinhart-Hart equation, B-parameter equation), or a freely programmable conversion table. Sensor malfunctions such as broken wires are indicated by error LEDs.
