Two-channel analog input module 0-20 mA. Installed injunction boxes and cable channels, connected via Modbus RTU.
Used to connect sensors with 0-20 and 4-20 mA output in dispatch systems for engineering systems and process control.
Main characteristics
- You can connect 0-20 mA and 4-20 mA sensors.
- Can be mounted in junction boxes and cable ducts.
- A filter for channels with an adjustable averaging time allows you to filter out sharp current surges caused by interference.
- Can be used with controllers from other manufacturers.
- Wide range of supply voltages (9-28 V).
- Fast and simple integration into the automation and monitoring system.

We develop and manufacture all Wiren Board devices ourselves. All devices undergo multi-stage quality control:
- During development — checking the components used for compliance with the declared characteristics and testing the prototype device at extreme operating conditions.
- After installing SMD components — automated optical inspection.
- After soldering the lead components — visual inspection of soldering.
- After assembling the device — functional testing on an automated stand.
- When shipped to the warehouse — control of completeness, stickers, appearance.
Thanks to this approach, the failure rate is no more than 0.5% of all released devices. Read more in the article About device reliability.
If the device fails within two years from the date of purchase, we will replace it for free without the need to send it to a service center.
When used with a Wiren Board controller, you can use the mouse in the web interface:
- enable or disable input polling,
- adjust the exchange speed.
When used with other equipment, the device can be configured via the RS-485 bus by writing values to Modbus registers. The register table is open, well documented and available on our website.
If a Wiren Board controller is used, the measured values are available in the controller's web interface and can be used in automation scripts or transferred to a higher-level system. Only the included channels are displayed in the device card.
The module also transmits all data via Modbus RTU (RS-485), which can be read by any equipment or software that supports this protocol: third-party controllers, HMI panels or SCADA.
