Timer relays help to protect industrial equipment from various issues, such as the effects of high starting voltages. However, such protective effects can only be possible if the right timer relay is selected for the application. This article discusses how timer relays vary based on how they can be installed in a panel. Use this information to select timer relays that will be easier for you to install on your industrial equipment.
Plug-In Timer Relays
Plug-in timer relays require a socket that has several pins. For instance, some relay sockets may have 8 pins while others have 11 pins. You must therefore ensure that the specific timer relays that you buy can fit into the sockets available on the equipment panels in your industrial plant. The biggest advantage of plug-in timer relays is that they are very easy to install or replace. This is because it isn't necessary for you to tamper with the control wiring inside the panel.
Encapsulated Timer Relays
Encapsulated timer relays are fully enclosed so that their operating mechanism can be protected from extreme operating conditions, such as the existence of chemical fumes within an industrial plant. They are also suitable for crowded panels where space is limited. This is because the timer relay is compact in design. They are also the most suitable type of timer relay in case you would like the relays to work for an extended duration. However, their installation is more complex when compared to other kinds of timer relays.
Modular Timer Relays
Modular timer relays are narrow and compact. They take up the least amount of space within a panel when compared to other types of timer relays. These timer relays are designed to fit into a DIN track inside the panel of your industrial equipment. They are also relatively easy to install since they fit easily into the connector in the panel.
1/16 DIN Timer Relays
1/16 DIN timer relays are the relays of choice if you would like to get easy access to the switches or the display of the relay on your equipment. This is because the relays can be installed outside the panel. They are installed using wires that protrude from the back of the relays. Those wires enable the timer relays to be mounted on the panel door.
Other factors may also influence your choice of timer relay, such as the trigger signal that activates or deactivates the timer relay. It is therefore advisable for you to talk to an expert so that you can have all the relevant information that you need to make an informed decision about the most appropriate type of timer relays for your industrial equipment.
