AT-16003 – 8-Channel Thermocouple Input Module with Modbus RTU
The AT-16003 is an 8-channel thermocouple input module designed for precise and reliable temperature measurement in industrial automation systems. Supporting a wide range of thermocouple types — K, J, N, R, S, T, B, and E — it offers flexibility for various process and environmental monitoring applications.
With a 19-bit resolution and an accuracy of ±0.7°C, the AT-16003 ensures highly stable and accurate readings across extensive temperature ranges (up to 1800°C depending on thermocouple type). It communicates over Modbus RTU (RS-485) and features Automatic Data Direction Control (ADDC) for smooth and efficient data exchange.
Built with galvanic isolation, TVS/ESD protection, and a rugged mild steel DIN-rail mountable enclosure, this module is ideal for harsh industrial environments requiring dependable temperature monitoring.
