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.

Selection FAQ

How should this product be selected?Selection normally starts from the field object: control loop, input signal, sensor type, weighing point, meter circuit, communication method and platform requirement.

Can it connect to an IoT platform?Zhenming products can be combined with platform functions for remote control, status viewing, schedules, alarms, logs and data management.

Is private deployment supported?Private deployment and system integration can be planned according to project scale, network condition, interface scope and maintenance workflow.
