Description
technical field [0001] The invention belongs to the field of using safety of a centrifugal fan, and specifically refers to a control system of a triggering alarm type centrifugal fan. Background technique [0002] In recent years, programmable logic controllers have been widely used due to their many excellent features, and have become standard equipment for industrial control in industrially advanced countries. It is specially designed for industrial control, integrating electrical, instrumentation and control, and is an ideal control device for realizing mechatronics. [0003] Conventional centrifugal blowers, referred to as centrifugal fans, mostly use traditional relay control circuits in their control systems, and a large number of intermediate relays and time relays are used in traditional blower relay control circuits. Failure and accidents are prone to occur due to poor contacts. Due to the extensive use of traditional relays, the control system is bloated and comp...
