Endress+Hauser’s RIA45 and RIA46 display units are easily read from a distance due to the large digital display. Both indicators are suitable for a wide range of process applications either installed in the field or in a control room. Industries include chemical, pharmaceutical, food and beverage or any thermal processes.
The RIA46 has the option of either aluminium or standard reinforced plastic housing. Both indicators adhere to safety certification and therefore are able to operate in hazardous conditions. Ease of configuration ensures quick commissioning; the devices can be set-up using Endress+Hauser standard ReadWin software.
Inputs and outputs are galvanically isolated from each other. Both indicators are dual input/output; outputs can be relay or analogue. This allows the units to be used in a wide variety of applications including those that require mathematical functionality as well as linearisation.
The backlight 5-digit 7 segment LC display indicates process values in high contrast. Measured or calculated values are shown in white and black while additional information such as TAG numbers, bar-graphs and unit identification are shown in yellow. On the front of the instrument there are membrane switches which enable the user to program the unit manually.
Supply for the indicators is either 24 VDC loop powered or mains 240 VAC. The onboard 24 V power supply can be used to power transmitter loops. The indicators are self-contained as they have a battery back-up to ensure values stored within the unit are not lost during power outages. In addition, peak values and occurring events can be logged. Universal inputs allow configuration of the instrument to 0/4-20 mA current signals, voltage, resistance, RTDs and thermocouples.
