AT-11013 / AT-11023 – 8-Channel Analog Input Module with Modbus RTU
The AT-11013 (Current Input) and AT-11023 (Voltage Input) modules are compact, high-precision 8-channel analog input devices designed for accurate signal acquisition and seamless integration with Modbus RTU systems. Each channel can be configured independently, supporting multiple input ranges — 0–5V, 0–10V, 0–20mA, and 4–20mA — to meet diverse monitoring needs in industrial environments.
Featuring 12-bit resolution and high measurement accuracy (±0.1% for voltage and ±0.2% for current), these modules ensure reliable data collection for control systems. Built-in TVS/ESD protection and galvanic isolation safeguard both the module and connected equipment from electrical disturbances.
With RS-485 communication, Automatic Data Direction Control (ADDC), and a serial configuration utility, the AT-11013/AT-11023 offer easy setup and stable communication. Their rugged mild steel enclosure, wide 9–36 VDC operating range, and DIN-rail mounting make them ideal for harsh industrial environments.
