This is the Bestact relay, chosen for its long lifespan and stable contact resistance for FA equipment that requires frequent opening and closing!
- Solving the issues of short lifespan and contact failure in relays used in FA equipment control panels. - Reducing running costs of equipment and mitigating recent material procurement risks by decreasing replacement frequency. - FA market relays leveraging product technology that excels in railways, power, and steel, where long lifespan and high reliability are required. ■ FA Equipment Adoption Case 1 It has been adopted for the opening and closing control of electromagnetic valves. Before adoption, a protective circuit was necessary to counter surge voltage when the electromagnetic valve was opened, and contact failure in general relays caused the electromagnetic valve to malfunction. With the adoption of the Bestact relay, direct control of the opening and closing of the electromagnetic valve became possible without a protective circuit. Additionally, contact failure has improved, leading to stable operation of the electromagnetic valve. ■ FA Equipment Adoption Case 2 It has been adopted for the switching relay of linear motors used for transporting vegetable bases in a vegetable factory. Before adoption, the relay was replaced every three months due to high opening and closing frequency, and contact failure occurred due to the humid and harsh environment. With the adoption of the Bestact relay, mechanical lifespan and contact failure have been significantly improved. The replacement cycle has been greatly extended, leading to reduced maintenance costs.
