4- 20 mA Double Phase Solid State Relays


4- 20 mA Double Phase Solid State Relays


Buyers can obtain 4- 20 mA Double Phase Solid State Relays at market-leading rates from us. These are manufactured in adherence with set industrial norms. One can obtain these at nominal rates from us.

 

Details :

  • Solid State Relays (SSRs) are switching devices consisting of electronic components. The term "Solid State" means that these relays do not incorporate any moving parts in the load switching circuit.
  • When applied properly, Solid State Relays (SSRs) will last millions of cycles due to the fact that no mechanical devices are included in the load switching circuit. The user will experience no arcing problems, and operation will be troublefree , even in polluted environments (dust,gasses, etc.)
  • Furthermore, Solid State Relays (SSRs) increase operating speed there by providing the  phase angle switching Firing . A Solid State Relay is the solution when the system designer needs to switch loads rapidly.as in all kinds of temperature control applications. Solid State Relays are used extensively in the Plastics, Packaging, Food Processing and HVAC industries and are an excellent replacement for electromechanical relays.
