Advancement of technology does not always mean that the equipment which was used earlier has become redundant. In the case of EMRs, this statement is correct. Relay technology has undergone substantial changes in the past 3 to 4 decades. The advent of specialized modern pieces of equipment has changed the landscape completely.
Electromagnetic Magnetic Industrial Switches
Class is permanent
Electromechanical relays are still in demand because of the full range of practical applications for which they can be utilized. Whenever technicians want relays that can serve them in case of general needs, they opt for electromechanical relays.They are also known as electromagnetic switches because they use energy in this form to operate.
Transmission of signals using EMRs
The use of electromechanical relays has not undergone any decrease despite the arrival of solid state relays. The ability of electromechanical relays to transmit signals efficiently has allowed them to stand the test of time. Their durability also makes them a viable option for most technicians. When there is a need to test automated equipment, all expert mechanics and engineers prefer using electromechanical relays.
EMRs are forever
It is safe to say that EMRs are here to stay for a long time to come. You must bear in mind that the resistance, as well as the capacitance of EMRs, make them unique in many ways. Their efficiency at switching loads allows them to be used in many machines. Operating electromechanical relays is slightly complicated, but their effectiveness makes them accessible.
SSRs vis-a-vis EMRs
The capacitance of SSRs is nowhere near the value possessed by electromechanical relays. Their resistance is also not up to the mark for many purposes. It is evident that solid state relays are valuable in their way for a small range of utilities. An expert will always select the most suitable equipment keeping in view the requirements of the project. So, you must understand that comparing them will not give any practical solutions.
Apt tools for suitable times
The truth is that their applications are separate with some common elements. The aim of an electrical engineer should be to make optimum usage of both of these excellent pieces of equipment rather than attempting to draw parallels between them. SSRs are different switches because they provide ease in operation. They allow technicians to switch the load in minimal time. EMRs are brilliant because of their efficient modus operandi even though they take more time to finish switching.
