Defective devices (not electronic components) are (according to the manufacturer's warranty) exchanged or repaired.
Relay isolation drive control module, the core is electronic control devices relay，there are control system ( called input loop) and controlled system (called output loop), Essentially an "automatic switch" that uses a small current to control large currents. This design have output signal indicator prompt,adopt dual power supply selection and optocoupler design, enhance anti-interference and isolation performance. can be used for signal amplification of MCU ,PLC, industrial computer and other equipment.
