In today’s video we are going to be discussing signal conditioning for industrial control signals. In some of our other video’s we have discussed several different types of control signals in more detail, for more information on those signal types, please click on the link in the description below. In many cases you can simply receive data from the sensors or transmitters you have in the field.
However, there are situations where the signal will encounter issues as it is transmitted back to the controller or PLC. Signal conditioning devices can be used in these situations to assist in avoiding some of the complications that can arise. Today we will discuss the most common types of signal conditioning devices... and what they are specifically used for. These devices include: signal isolators, signal amplifies, signal converters and signal splitters. We will briefly discuss the purpose of each... and applications you might want to use them.There are other categories of signal conditioners which we will not discuss in today's video.
First let’s talk about signal isolators. Signal isolators are used for many different reasons and are one of the most common types of signal conditioning devices. One of the main reasons you would use a signal isolator is to protect sensitive equipment, such as a PLC form potential hazards that may originate at a device it is connected to… such as a sensor or transmitter.
The isolator separates the signal generating device from the controller, thus protecting it. Isolators can also be use to filter any noise that might arise from any disturbances along the signal path back to the PLC. They can also filter electrostatic interference that can be caused from ground loops which can detract from the accuracy levels of the signal you are trying to detect. These ground loops can also potentially cause damage to any devices they interact with. It is common to see signal isolators in both 2-wire and 4-wire configurations. With the 4-wire setup, it is necessary to provide separate power to the isolator. Conversely, when using the 2-wire setup, you have the ability to supply loop power.
Another type of signal conditioning device is a signal converter. Like its name would suggest, a signal converter will take one type of signal, and change it to something else. So why would you need to change the signal type? Let me give you an example. Let’s assume you have sensor in the field measuring temperature… and the sensor you are using is an RTD (resistance temperature detector). Also in this scenario lets say the PLC you are using does not have the ability to read RTD signals. In this case you need something that can interpret the RTD signal and convert it into something that the PLC can understand (possibly a 4-20mA signal). In this case a signal converter would be used to to perform this signal conversion. There are several different types of signal converters with varying degrees of functionality. In some cases, the signal converter has the ability to read multiple signals types and can be configured to send multiple output signals types… giving you several options with only one device. Conversely, there are signal converters that only have the ability to read one input signal type… and convert that to only one output signal type. So, it is important to select the correct converter that will best fit your needs.
Next, let’s talk about Signal Amplifiers. A signal amplifier has two main functions that it can perform. The first is to increase the resolution of the input signal. This will allow for more accurate and detailed data to be sent to the controller which enable you to better monitor and control these devices.
Lastly, let’s talk about Signal Splitters. A signal splitter does not technically fall in the same category as the other types of conditioners. The other devices that we have already discussed will alter or change the signal in some way. However, a signal splitter does not change the signal, it simply allows you to send the signal to more than one location. For example, if you have a signal that needs to be monitored by a local PLC as well as another PLC in a remote location, a signal splitter can be used to send the data to both PLC’s without any signal degradation.
