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

Communication AccessSelect RS485, Ethernet, 4G, WiFi, HTTP or MQTT according to the device type, site network and platform integration requirements.

Field DeploymentProducts can be combined by control loop, sensor point, weighing point, meter circuit, cabinet layout and project maintenance workflow.

Platform ManagementRemote status viewing, schedules, logs, alarms, data curves and account permissions can be configured according to project requirements.

Customization ScopeProject configuration can cover model selection, interface coordination, platform deployment, panel interaction and integration documents.

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.
