With as many devices as we offer, it may feel like quite an accomplishment when you narrow it down to a few options! After that, the concern comes to the specifications of the device and how to differentiate them from one to another. In this week’s Tech Tuesday post, I would like to help you better navigate our data sheets in order to quickly determine the correct device for your application.
Below you will see the RIBU1C relay device data sheet. It’s a two-in-one data sheet, as both the RIBU1C and RIBH1C relay are featured on the sheet. You will see letters and circles on the sheet. This is not the standard – I only marked up the page to bring attention to some key portions. These points are in the order I look through when assisting someone through a technical call. Let’s take a look at a little “insider knowledge” and learn to navigate the data sheet to determine the best device for the job.
- Device Category: This category describes the type of device and how you may use it in the field. We have many categories of devices, so noting this may be helpful in narrowing down the right devices for the application.
- Part Number and Brief Description: The brief description states the relay rating, relay contact output configuration, and the operation voltage range. If you ever call into technical support, it’s also a good idea to have the part number handy.
- Wiring Diagram: For the relay devices, the relay coil input is on the left side and the relay contact output is on the right side. For other more complex devices, the wiring diagram will display the location of components that are important to its operation.
- Product Dimensions: Some individuals look for the overall dimensions of the product. Those measurements may get lost in all of the other accumulated data. All of our data sheets give the overall dimensions of the product.
- UL Approvals: This may be more important to some, but if the job needs a device approved for the application, look here to see if that specific UL Approval is covered.
- Device Contact Ratings: This is probably the most important section on the data sheet for any of our devices and is what I receive the most technical calls on. The different loads (i.e. resistive, pilot duty, lighting, motor, etc.) given here are specifically tested to the size of the relay, so that you may rest assured the relay will have a long life of switching!
- Coil Current: This section states the amount of current the device consumes by the coil of the relay so that the load on the contacts may be switched. This may be important if your job has a small transformer or power supply and you want to be sure the transformer can supply the necessary power to the device.
Now that you have an overview of the data sheets, I hope that next time you go looking for a device for the job, the search will be quick and easy! Of course, if you still need a bit of help, feel free to send us an email or give us a call. We’ll be glad to clear anything else up.
