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.
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.
The QL series provides multi-circuit remote switching over 4G. Select a model by circuit scale; use the relevant ranges for latching outputs or single-circuit energy monitoring.
The QCL series provides multi-circuit 4G latching control. Select by circuits and cabinet space; compare QC products for Ethernet sites and ER1 for single-circuit energy-aware remote control.
Choose an energy relay when one circuit needs both 4G switching and power data. Compare a switching-only controller for simple start/stop duties, or a multi-circuit energy controller for additional circuits.
The QL family brings a group of cabinet outputs onto a 4G management platform. Organize devices by site, building, pump station or distribution cabinet. Models from 2 to 32 channels support different circuit densities and phased deployment. Grouping several circuits in one controller also reduces the number of separate connected endpoints to manage.
4G provides the remote management path, while RS485 Modbus RTU serves local bus integration. Retain the required PLC, panel or gateway interaction and use the platform for grouping, remote operations and logs. Plan the supply, bus wiring, load routes and antenna position together. Matching platform names to electrical circuit labels helps remote operators identify the intended load.
03
Build a usable multi-site channel register
A channel register records the area, load name, normal policy and maintenance responsibility of every output. Platform groups can then mirror stores, campuses or equipment groups. Daily work follows connectivity, control records and planned operation. Contact feedback, current sensing or an energy module can extend the view from relay state to actual equipment behavior.
Selection questions
Are QL and QCL interchangeable at the same channel count?
No. Relay specifications, local inputs, interfaces and supply also matter. Select each family from its own model data.
How are multiple 4G controllers organized?
Group them by site, building, cabinet or equipment group, then assign clear field names to each output and use platform permissions and logs.
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.
Controller, bus and platform roles
Model-specific interfaces
Select 4G, Ethernet or RS485 by model. RS485 slaves use a networked host or gateway for platform access.
Circuit planning
Select IO count, load characteristics, terminal space and maintenance groups using the specific model drawings.
