The Endress+Hauser RIA16 indicator displays the measurement signal on the large backlit display. Fast process overview through bar graph. Editable plain text field for unit or TAG. In the event of a limit value violation, this is also signalled and an open collector can be switched. The indicator does not require any separate auxiliary power, but is supplied directly from the 4...20 mA current loop. For applications in hazardous areas, the device is available with Ex approval.
