Selection Notes for B2B Projects

Control ObjectPlan the product by lighting circuit, pump, fan, cabinet output or equipment switching object instead of only by channel count.
Protocol and PlatformCheck whether the project needs RS485, Ethernet, LTE(4G), MQTT, Modbus, grouped control, schedules, logs or private platform deployment.
Circuit PlanningSeparate high-power, inductive and frequently switched loads into clear circuits and match controller selection with the cabinet design.

Integration and Deployment

Circuit ObjectsMap each output to a named lighting, pump, fan, valve, cabinet or equipment circuit and retain a clear control boundary.
Local OperationUse dry-contact inputs, wall panels, schedules or supported local rules for field operation when the selected model provides them.
Network OperationsUse the communication interfaces of the selected model for status, remote control, action records and multi-site management.
Electrical CoordinationCoordinate relay loads, contactors, protection, cabinet wiring and manual override with the electrical design.

Protocol and Lighting Strategy Notes

Relay controller projects can be combined with DMX512 lighting control, sunrise and sunset schedules, Modbus integration, MQTT access, platform management and operation logs.

Remote Device Intercontrol

Supported models and firmware can map a remote input, sensor or business event to controller outputs at another site for one-to-one or one-to-many linkage. Applications include water towers and pumps, parking counts, warehouse alarms, irrigation and chain-store equipment.

Selection FAQ

What lighting or control projects are suitable?These relay controllers are used for smart lighting, control cabinets, equipment switching, parks, streets, campuses, hospitals, cinemas and exhibition halls.
How should relay channels be selected?Channel count should follow the number of lighting circuits, equipment groups, cabinet layout and expansion margin.
Can the controller support remote operation?Depending on the model, RS485, Ethernet, 4G, MQTT, TCP, UDP or platform access can support remote control and status viewing.
