Programmable relays are important automation devices
with multiple inputs and outputs that help combine counter, timer, and relay functions. Most of them are designed with a small quantity of I/O points while others have more than 20 discrete and analog inputs as well as outputs. The design of most programmable relays
have LCD displays that show the program and configurations. Besides, the relays also come with buttons and keys on the face for easy navigation actions such as entering the program, editing program parameters, starting, configuring, and stopping the device under consideration.The compact design of programmable relays means they are easy to install with minimal wiring. They are also easy to use and can be connected to other automation devices in your facility. Note that just like computers, the programmable relays come with some limitations. Therefore, understanding the specific application as well as different variables is crucial. For greater efficiency, you should look for the programmable relays that are designed to work with your devices.
