Most customers who need a field device want one with a display built in. It’s not necessary, but what if you want one and your device doesn’t have it? Rather than change the device, you can add a universal display.
Indeed, you can find many opportunities to install this sort of display, but beefing up an old installation to help an operator is top of the list.
Today, let’s review the RIA15 from Endress+Hauser, a local or panel indicator that can read analog and HART values. Stick with me to find out the pros and cons of this product.
How is it?
As usual, we’ll start by examining the design. Most of the time it makes little difference, but in some cases, it can save space and provide a better user interface.
The RIA15 comes in two versions. The panel version has its dimensions at 96 by 48 by 41.5 millimeters (mm), but the field version has an additional housing, making it 131 by 81.5 by 55.5 mm. Either way, this compact device doesn’t need much space.
On top of that, you can configure it using local operation keys. The keys follow the Endress+Hauser standard, so if you’ve used E+H devices, you’ll breeze right through it. Even if you haven’t, the configuration is so straightforward that you won’t need the manual at all.
What can it do?
The RIA15 can display data for many types of field devices and communicate through analog or HART protocol. Beyond that, it uses loop power, which means it doesn’t require an external power supply. The juice in your field device’s loop will power it up, but check for the voltage drop before installing it.
It has a single input for the communication. If you have an analog device, it will show only one process variable, but you can decide the unit that it displays. Now if you have a HART device, you can display up to four variables. For instance, if you get a Coriolis flow meter, it can provide you the mass flow, volume flow, temperature, and density.
With HART, you can have two masters in the network, the primary and secondary HART master. Usually, you’ll set it up as the primary master, and then the handheld will work as a secondary master. But you can switch it up, depending on the architecture of your solution. We like having this sort of flexibility on a device’s configuration.
Why should I care?
As a universal display, it can read data from any device that uses analog or HART protocols, which represents a good percentage of the devices out there, right? And its flexible installation and simple configuration should save you time setting it up and getting it started.
Additionally, the display has a five-digit measured value display and a bar graph. Plus it has a backlight you can activate. Best of all, if you need particular approvals, you’ll find ATEX, IECEX, FM, CSA, GL marine approval, and more. You can see the entire list on the device page here.
If you want a flexible and compact display with analog or HART communication, then the RIA15 will make a great option for you.
