Description
The PID Temperature Controller is a compact panel-mounted controller designed to measure, regulate, and maintain accurate process temperatures in industrial heating and cooling applications. Supporting both RTD and thermocouple inputs, the controller provides precise temperature regulation using either PID (Proportional–Integral–Derivative) or ON-OFF control, allowing users to select the most suitable control method for their process. Its 48 × 48 mm DIN panel size makes it ideal for compact control panels, OEM machinery, and industrial equipment where installation space is limited.
The AI-7482 PID Temperature Controller features dual control outputs, including a configurable Relay or SSR drive output for primary process control and a dedicated relay output for alarms, auxiliary functions, or secondary process operations.

FAQs
1. What is a PID Temperature Controller?
A PID Temperature Controller is an electronic temperature control instrument that continuously measures process temperature and automatically adjusts its control output to maintain the desired temperature setpoint with high accuracy. It is widely used for precise temperature control in industrial process automation.
2. What is the difference between PID and ON-OFF Control?
PID control continuously adjusts the control output to minimize temperature fluctuations, overshoot, and steady-state error, making it ideal for precise process control. In contrast, ON-OFF control simply switches the output fully ON or OFF when the process temperature crosses the setpoint, making it suitable for simpler temperature control applications.
3. Which sensor inputs are supported?
The PID Temperature Controller supports both RTD sensors and thermocouple inputs, allowing it to be used with a wide range of industrial temperature sensors for process heating, cooling, and automation applications.
4. What outputs are available?
The controller provides a configurable Relay or SSR (Solid State Relay) drive output for primary temperature control, along with a separate relay output for alarm indication, auxiliary control, or process safety functions, offering flexible integration with industrial control systems.
