LORDWORLD 4CH Modbus RTU DC Monitor 36V 8A 16-bit DIN Rail

SKU CH-GFJV-PJ9M0

Four-channel DC monitor measures voltage, current and power over isolated RS485 with 16-bit precision and DIN rail mounting

  • 4-channel DC voltage, current and power monitoring via RS485 Modbus RTU
  • 16-bit ADC with built-in 0.002 Ω shunt enables precise bidirectional current measurement
  • Measures up to 36 V and 8 A per channel with direct power readout
  • 7–36 V wide supply input with dual power and optocoupler isolation for robust RS485
  • 35 mm DIN rail case includes resettable fuse, TVS surge protection and status LEDs

Four-channel Modbus RTU DC monitor

This module measures DC voltage, current and power on four independent channels and reports the data over a wired RS485 link using the Modbus RTU protocol. It is aimed at automation engineers and system integrators who need reliable DC energy metering in industrial or laboratory environments.

Check supply voltage and bus wiring

Verify that the available DC supply falls within the 7-36V input range and that the RS485 bus uses the same Modbus RTU settings as the host controller. Confirm that each monitored circuit stays inside the 36V and 8A bidirectional limits and that the 35mm DIN rail space can accommodate the stacked enclosure.

Replaces single-channel meters

The jump is worth it when you must monitor four circuits simultaneously with 16-bit resolution and a built-in 0.002 shunt, while gaining dual isolation, a resettable fuse and TVS protection that simpler shunts or unprotected meters lack.

Questions about this item

Does the module ship with RS485 cables or a DIN rail clip, or must they be sourced separately?

The unit includes the 35 mm DIN rail housing with integrated clip; RS485 wiring and any terminal plugs are not supplied and must be provided by the installer.

Should I pick a different model if I need more than four measurement channels or higher voltage than 36 V?

This model is fixed at four channels, 36 V maximum input and 8 A bidirectional current; applications requiring additional channels or higher voltage need a different device.

What does the 16-bit ADC and 0.002 Ω shunt mean for real-world current resolution on each channel?

The 16-bit converter combined with the 0.002 Ω sense resistor provides fine-grained bidirectional current tracking across the full 8 A range on all four channels.
