12-channel AC energy acquisition module for three-phase voltage, 12-channel current, power and energy monitoring with RS485 or LTE(4G) access.
The page is written for engineering companies, system integrators, device manufacturers and B2B project procurement teams.
Use the module for separate single-phase branch measurements rather than only a distribution total. Plan branches, current transformers and reporting dimensions; compare three-phase systems for whole three-phase loads.
Use this system for centralized three-phase power measurements. Separate whole three-phase monitoring, multiple single-phase branch metering and power-quality analysis by distribution wiring and measurement boundaries.

ZMSG1212-12S3 combines three-phase bus voltage with twelve external CT channels to record current, power and cumulative energy for single-phase branches. Separate lighting, HVAC, sockets, fans or auxiliary equipment rather than relying only on a main meter. Match each current channel to its actual phase and load name.
Correct voltage/current pairing is central to multi-circuit acquisition. For every branch, record phase, CT channel, range, load and purpose, then compare local and platform values. Update the register when circuits or CTs change. The module measures; a separate relay controller can switch the circuits, with the supervisory system correlating control and energy.
The color screen supports field inspection. RS485 connects to a PLC, gateway or supervisory system; a 4G version serves distributed cabinets. Organize platform data by building, floor, zone, cabinet and end use. Compare after-hours consumption, similar equipment or policy changes using consistent periods and comparable load conditions.
Lighting projects can review energy after schedules or scenes. Farms can separate fans, cooling pads, heating and feeding lines; factories can distinguish auxiliary equipment from common services. Energy trends provide clues, while control logs and field conditions explain them. Consistent groups and channel names support expansion from one cabinet to multiple sites.
No. It serves twelve single-phase branches, pairing the shared voltage inputs with the corresponding current-channel phases.
A total describes the overall load. Submetering associates measurements with individual equipment or end uses for operating analysis.
RS485 fits sites with a PLC, gateway or field bus. 4G fits distributed points requiring remote platform access.
Three-phase totals, twelve current channels and dual-circuit energy address different objectives. Map channel phases before grouping data.
Select measurement input, device supply and communications separately; 12V DC and 220V AC models are not interchangeable.
