Eastron — equipment and components

Communication gateways and converters Eastron

Select Eastron ESP gateways to connect meters to Ethernet, Wi-Fi or cellular networks. Specify the source interface, protocol, number of lines and the receiving system.

Communication gateways and converters

Choose a gateway between two defined ends of a connection. List devices, physical interfaces and protocols on each side. Replacing a cable with a wireless link still requires checking addresses, timeouts and receiving-software requirements.

ESP-E11

A compact DIN-rail gateway from Modbus RTU to Modbus TCP. It connects RS485 instrument data to Ethernet. For replacement, provide the serial settings and how the supervisory system addresses the devices.

ESP-W11

A DIN-rail RS232/422/485-to-Wi-Fi converter. Identify the actual serial interface and describe the wireless network the gateway will join.

ESP-G41 / ESP-5100

Cellular options: ESP-G41 lists RS232/485 to 2G/3G/4G, while ESP-5100 lists RS485/232 to 3G/4G. Specify the operating country, mobile operator and network-access requirements.

ESP-2100

A serial server for RS485 Modbus RTU and Ethernet TCP/IP. System integration requires the exchange mode, device list and polling settings.

ESP-2200 / ESP-2400

Multiport devices: ESP-2200 lists two serial and two Ethernet ports; ESP-2400 connects four RS485/232/422 ports to Ethernet. Select according to the number of independent lines.

ESP-65 / ESP-4104

ESP-65 is a LoRaWAN gateway; ESP-4104 is an RS485-to-Wi-Fi converter and serial server. Specify the frequency plan and network server for LoRaWAN, or the site network requirements for Wi-Fi.

Choose the equipment group

For consumption metering, start with SDM or DCM and define AC or DC operation and the connection method. Consider Smart X when the project requires network parameters and harmonic readings. If the instrument stays in place but an external sensor needs replacing, use the current-transformer group.

An ESP gateway transports data already measured by another device. The monitoring group covers projects with multiple measurement points. Time-delay and weekly-schedule tasks belong to ESRD and ESRS. This separates the required device from its function in the wider installation.

Specify an installed-device replacement

Photograph the front and side identification, terminal markings and the installation space. Transcribe the full model suffix. If the circuit includes CTs or a shunt, identify those components separately; the meter name alone does not define the complete measurement set.

State whether you need one instrument, a set with sensors or equipment for several identical panels. Describe an observed failure such as a blank display, missing communication or inconsistent readings. This helps distinguish a replacement purchase from a measurement-chain investigation.

Current input, protocol and scope of supply

Separate the primary current from the signal reaching the instrument. Inputs rated at 1 A / 5 A, 40 mA, 100 mA, 100 mV and Rogowski-coil inputs require the corresponding sensors. The power-circuit current rating alone does not specify the instrument variant.

For RS485, provide the protocol, addresses, speed and communication format. For Ethernet, define the device role and receiving system. List the meters, sensors, connecting cables, converters and mounting items actually required as separate entries in the scope of supply.

Inverter and charging-station projects

For an inverter, identify the exact model, software version and meter location in the power diagram. Include the supported-device list from the inverter documentation where available. Compatibility assessment concerns the specific device pair, including registers and energy-flow direction.

For a charging station, state AC or DC operation, the working range and power connection. Add any need for a separate display or multiple communication ports. Compare market-specific variants using the complete ordering code and project documentation.

Prepare a sourcing request

Send the ordering code or photographs, required quantity and delivery destination. If identification is incomplete, include the relevant wiring-diagram section and explain the device function. For a new installation, provide a specification with a separate line for each instrument type.

The quotation should be compared with the requested variant and set contents. State whether an alternative may be proposed for engineering review. For multiple panels, distinguish the quantity per panel from the total procurement quantity.

Quotation and project confirmation

Availability, price, lead time, compatibility and included components are confirmed for the selected variant after reviewing the request. No authorized-dealer status is claimed. MID, UL/ETL or PTB/Eichrecht identification must be checked against the exact instrument and project requirements.
