Selection Notes for B2B Projects

Signal TypeConfirm whether the project needs digital input, relay output, analog output, frequency, pulse, sensor or energy data acquisition.

System AccessSelect communication and platform access according to PLC, SCADA, customer platform or Zhenming IoT platform integration requirements.

Project ExpansionReserve enough channel, protocol and platform capacity for later expansion when the site may add more devices or sensor points.

Integration and Deployment

Signal DefinitionConfirm the electrical signal, range, channel mapping and field terminal definition before cabinet design.

Bus PlanningPlan device address, communication parameters, cable route and host or gateway connection.

System MappingMap each channel to a clear sensor, actuator, meter or equipment object in the host system.

CommissioningVerify wiring, communication, data direction and control boundaries during system integration.

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.
