Supports Fast Modbus ⚡, which allows you to instantly deliver the effective voltage value to the Wiren Board controller.

Specifications:

• 4 active outputs 0-20 mA or 4-20 mA.
• Load resistance: up to 500 Ohm.
• 4 discrete inputs.
• Galvanic isolation of inputs.

• Supply voltage: 9…28 V DC.
• Interface: RS-485, Modbus RTU.
• Extended operating temperature range: -40…+80 °C.
• DIN rail housing, 3 modules.

All Wiren Board devices, in addition to the standard Modbus RTU, can work with its extension Fast Modbus ⚡, which adds new features:

• instant polling of input states and measured values via events;
• quick search for devices connected to the controller;
• resolving address collisions on the bus.

Additional features are enabled automatically - if the device supports extension, the controller driver will work with the device quickly Modbus if the device does not know anything about the extension - it will work using standard Modbus RTU.

All Wiren Board devices are developed and manufactured in-house. Each device goes through a multi-stage quality control process:

• During development — checking components and testing prototypes under extreme conditions.
• After SMD component installation — automated optical inspection.
• After soldering lead components — visual inspection.
• After assembly — functional testing on an automated test stand.
• Before shipment — verification of completeness, labels, and appearance.

Thanks to this approach, the failure rate is less than 0.5%. Read more in the article About device reliability .

If a device fails within two years from the date of purchase, we will replace it free of charge without the need to send it to a service center.

When used with the Wiren Board controller, you can use the mouse in the web interface to:

• set the operating range - 0-20 mA, 4-20 mA or custom,
• set the minimum and maximum current values,
• set the rate of change of current,
• set up the processing of button presses on the inputs and the interaction of inputs with outputs,
• enable and disable parameter polling.

When used with other equipment, the module can be configured via the RS-485 bus by writing values to Modbus registers. The register table is open, well documented and available online in the device documentation.

The voltmeter does not have its own screen, so reading the connected parameters is carried out via the RS-485, Modbus RTU interface.

If a Wiren Board controller is used, the measured values are available in the controller's web interface and can be transferred to the higher-level system. The device card displays only the channels enabled in the survey settings.

All data can be read by any equipment or software that supports the RS-485, Modbus RTU protocol: third-party controllers, HMI panels or SCADA.
