The relay box enables the control of up to 4 components for dosing or switching. The system can also be used, for example, to operate a grain dryer that removes moisture from grain based on weight. Simply enter the amount to be dried out, press start, and the WWA-1, together with its contacts, will handle the rest.
It features a highly legible display with a robust control unit, all developed and manufactured in our factory.
The weighing systems include load cells or weighing modules and everything you need to connect them to the display unit. The control unit can be connected by any electrician, and the entire system can be commissioned by the user thanks to its simple and intuitive operation.
The relay box includes 4 relays for controlling contactors, valves, etc., and is compatible with many evaluation devices such as the WWA-1, or RHEWA models 82b-2, 82c-2, 82e-2, 83sigma, and 84vario.
