A-10 Modbus DAQ Series Features

Voltage-Friendly Design
Operates on a wide voltage range: 10 – 30 V DC or 24 V AC, offering installation flexibility across diverse power environments.

Integrated Digital Inputs
Equipped with two isolated digital inputs capable of detecting low (< 1 V DC) and high (8–30 V DC) signals reliably—even in electrically noisy conditions.

Transistor Output Support
Includes two source-type transistor digital outputs for driving external devices such as indicators, small relays, or coils directly from the module.

Industrial-Grade RS‑485 Comms
Communicates via RS‑485 using Modbus RTU/ASCII protocols—perfect for robust industrial networking and seamless integration into SCADA or PLC systems.
