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 and system combinations
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.
Select L1 or L1D single-circuit 4G control by supply and load. Compare the energy-aware ER1 for power data and multi-channel 4G ranges for additional circuits.
Dual-circuit energy control combines switching with power measurements. Compare ER1 for single-circuit 4G energy control and branch acquisition products for additional metering circuits.

Product integration and applications
01
Combine switching and energy data at one load
ZMRL0101-ER1 combines a 220V supply, one relay output, one digital input and 4G access in a DIN-rail module. Voltage, current, power, frequency and cumulative energy add a load-level view to remote switching. Give each device a clear field name so that control, schedules and energy records refer to the same operating object.

02
Check device status after a control command
Maintained switching, momentary pulses and toggle mode cover distinct operating tasks. The digital input supplies a local switch or field status. Review output state, input changes and electrical measurements together after an action. Clear load names and input meanings help remote staff understand the field process and coordinate maintenance.
03
Weekly schedules and MQTT multi-site management
Up to 32 weekly schedules organize opening, duty, cleaning or equipment operating periods. LTE(4G) MQTT connects distributed modules to the management platform for connectivity, commands and measurement reports. An integrated system should handle command acceptance, state messages and energy records separately, then correlate them by device and time.
Selection questions
Can energy data be reviewed with switching records?
Yes. Correlate the same device’s voltage, current, power, frequency and cumulative energy with its control and state records.
Is ER1 a multi-circuit cabinet controller?
ER1 is a single-channel control and energy module. Use separate units or select a multi-channel controller and acquisition module for larger circuit groups.
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.
