ES-IGW-B1 · Data Concentrator

A Modbus and RS485 gateway for the meters and controllers you already have

The ES-IGW-B1 collects data from energy meters, drives and controllers over Modbus TCP and RS485, and sends it to the En-Stream platform. You configure it from a web dashboard.

Use cases

What the ES-IGW-B1 is used for

  1. Energy metering across a plant

    Read a chain of energy meters on one RS485 line and see consumption by department, line or building.

  2. Bringing PLCs and drives online

    Pull data from PLCs and VFDs that speak Modbus TCP or RTU, without replacing them.

  3. Multi-site rollouts

    Install a gateway at each site and see every site on the same platform.

  4. A start that grows

    Start with meters on the B1, and add an ES-IGW-E1 where a site later needs direct sensors or equipment control.

FAQ

ES-IGW-B1 FAQ

What can the ES-IGW-B1 connect to?

Devices that speak Modbus TCP over Ethernet or Modbus RTU over RS485, such as energy meters, VFDs and PLCs.

How is it configured?

From a web dashboard.

What power does it need?

5V DC at 3A.

When should I choose the ES-IGW-E1 instead?

When you need direct sensor inputs (0–20 mA / 0–10 V analog or 12–24 V digital), CAN bus, RS232 or relay outputs to control equipment. The ES-IGW-B1 reads data from existing meters and controllers.
