Analogue-to-RS485 Acquisition Module Options

Bring a selected analogue signal into a Modbus RTU system with a compact YR2166 conversion board.

✅ Match the sensor's output type - Separate 0-5 V, 0-10 V and 4-20 mA versions suit different analogue signals.

✅ Read through an RS485 link - Modbus RTU provides the described communication method for a compatible master device.

✅ Fit a small control assembly - A roughly 28 × 16 mm board occupies little space in a suitable enclosure.

Give an analogue sensor a digital connection

A controller with RS485 communication may still need a conversion stage for a voltage or current sensor. This board supplies that stage when the selected input type matches the signal.

Check power, grounding and register scaling before connecting the system. The receiver's software must interpret the converted value correctly, and the board remains a component that needs appropriate mounting and electrical protection.
