Tutorial notes
Control and measurement in one module
This single-channel 4G energy relay from Zhenming Electronics combines remote control and electrical data acquisition in one DIN-rail module for distributed equipment.
A two-way control and data connection
A phone or web management interface sends commands through the platform. The relay connects over 4G, controls a single load and reports its output state and electrical data.
Remote switching and reported status
One relay output supports on, off, momentary operation and toggling. Output changes trigger reporting so the platform can display the state reported by the device.
Five measurements for electrical visibility
The device acquires voltage, current, power, frequency and accumulated energy. Together with the output state, these readings help operators observe electrical use and load operation.
Weekly schedules and a local input
Up to 32 weekly schedules execute output actions on selected days and times. One digital input provides a local trigger, and input changes can trigger status reporting.
Remote management for distributed equipment
Applications include distributed lighting, pumps, fans, outdoor equipment boxes and single-load connectivity. Select the product and system combination for the site's network, load type and control needs.
