## Overview

The ATR121-AD is a compact, high-precision PID controller designed for versatile industrial applications. It supports a wide range of temperature sensors and analog inputs with 16-bit accuracy, features dual relay outputs for powerful control, and offers advanced PID algorithms optimized for fast transient and stable process management. With programmable inputs and RS485 Modbus communication, it integrates seamlessly into modern automation systems, making it the go-to choice for professionals demanding reliability and flexibility.

## Description

This 32x74 controller is characterized by high configurability, which results in a small number of product codes. The input is programmable for temperature sensors, temperature and thermocouples but also for pressure transmitters, humidity and flow sensors. The hot-cold PID adjustment algorithm is optimized for both temperature control and fast transient process control such as pressure regulation and flow regulation. Among the software features of the ATR121 is also available the open-close logic for valve control on industrial thermoregulation, air conditioning, dosing systems. Controller outputs are selectable as command / multiple alarm/event modes. The serial communication option is in RS485 with Modbus/Slave protocol.
