How Process Transmitters Can Provide A High Voltage Output Up to ±20V DC?
Defining the Problem:
We are developing a 12V DC battery simulator that reaches 14.4V when charging. Our controller output cards are limited to 10V and we need a device that can step up the output to 15V. Typical process signal conditioners have standard ranges of 10V maximum. We require a device with a higher output voltage. For reverse polarity simulations, a bipolar output is preferred.
The SP330 Splitters have two independent and isolated outputs. For voltage outputs, the maximum output range is 10V. With two floating outputs connected in series, the total output voltage can be as high as 20V. Configuration can be performed via the Acromag Agility™ mobile application for Android® devices or with a Windows® PC.
Implementing the Solution:
1. Firstly, using the Agility mobile application or Windows software, scale the two outputs to sum to the output voltage required. See screen captures above for a ±15V output.
2. Secondly, the two independent outputs can be the same or different voltages.
For example, +10 and +5 = 15V output.
3. Thirdly, below is the output wiring. Complete the input, power and earth ground wiring as detailed in the user manual.
4. Fourthly, validate the I/O before connection to the test simulator.
In conclusion, the SP330 Series is a cost effective, high performance family of four-wire signal splitters. Using a Windows® or Android® device, set up can be done with a PC, phone or tablet. With many innovative features, these standard off-the-shelf products can be customised for a wide variety of applications.
