Automation gives us a wide range of options to solve a problem. For instance, when you have a new field parameter to measure, you don’t need a sensor and a transmitter to connect this new measurement into the control system.
The Weidmuller ACT20M-UI-AO-S is a simple and cheap way to make this happen is connecting the sensor directly into the control system. On the downside, in a few cases it can cost more and create different types of problems, so don’t jump straight into this idea without research! Luckily, we can help you with that as well.
In today’s article, we’ll review a product on the premise that it would be better to hook the sensor directly into the control system. We’ll also review one straightforward, low-cost solution on the market, the ACT20M-UI-AO-S from Weidmuller. This analog signal converter can convert different types of signals into one standard output.
What is theWeidmuller ACT20M-UI-AO-S?
You can call the ACT20M-UI-AO-S either a signal converter or a universal transmitter. Basically, if you connect different types of signals into it, then the converter will provide you with one standard output.
For instance, if you have a thermocouple, rather than use an extension cable, you can set a converter between the control system and the thermocouple. It will help you save money and avoid possible problems with cabling on this type of installation.
The Weidmuller ACT20M supports input signals such as current, voltage, resistance, various thermocouples, and temperature sensors. This product can install on TS 35 DIN, and its compact design (114.3 mm by 6.1 mm by 112.5 mm) should make it fit perfectly in your panel.
Its power supply requires 24 volts of direct current (+-30 percent), and you can connect it using wiring connectors or the DIN-rail bus. You can pick the option that fits better in your application.
What can the ACT20M-UI-AO-S do?
As I mentioned before, this universal transmitter is designed to install on a DIN rail. You can also use this device to convert a signal from 1-5 volts to 4-20 milliamps.On top of that, you can configure it using FDT/DTM software. Just download the WI-Manager from the Weidmuller website. Furthermore, you’ll need a CBX200 USB interface to connect the ACT20M to your computer.
When you have access to the device configuration, you can see all the data for your device. From here, you can set up the type, limit, and unit of the input and output. You can also check its diagnostics to make sure it’s working properly.
When might I need the ACT20M?
Any time you have to connect different types of sensors in the field into the control system using a standard output, such as an analog signal.
