EL3182 | 2-channel analog input terminal 4…20 mA, single-ended, 16 bit, HART

HART communication protocolThe EL3182 analog input terminal for HART-capable field devices supplies measuring transducers located in the field and transmits their analog measuring signals electrically isolated to the automation device. With a technical measuring range of 107 % of the nominal range, the terminal also supports commissioning with sensor values in the limit range and the evaluation according to NAMUR NE43. The HART (Highway Addressable Remote Transducer) protocol enables two-way communication through digital data transfer via the analog 4…20 mA wiring. The TwinCAT FDT container enables the integration of field device DTMs into TwinCAT Engineering, so that the device configuration and diagnostic functions are available directly within the development environment. The power contacts of the EL3182 can optionally be supplied with operating voltage in the standard way or via a power feed terminal (EL9xxx) with electrical isolation. The input electronics are independent of the supply voltage of the power contacts. The reference potential for the inputs is the 0 V power contact. The EtherCAT Terminal indicates the signal state by means of light emitting diodes. Error LEDs signal overload and wire breakage, in addition to which LEDs provide information about the state of the HART communication and signal any communication errors.
