An Elevator Relay Card is an electronic component used in elevator control systems to manage the operation of various functions such as motor control, door operation, and safety features. It is designed to withstand the electrical demands and environmental conditions typically found in elevator systems. This contains multiple relay outputs that can control various devices, such as motors, lights, and alarms, based on the elevator's status. They are commonly used in office buildings, shopping centers, and hotels for controlling passenger elevators. Elevator Relay Card is used in industrial and commercial freight elevators, where robust control systems are essential for handling heavy loads.
