PID Controller / PLC Module for Heating Systems

Product Specifications

Technical details and manufacturing context for PID Controller / PLC Module

Definition

This industrial control component integrates Proportional-Integral-Derivative (PID) control algorithms with Programmable Logic Controller (PLC) capabilities, serving as the intelligent control core within Heating Element & Control Systems. It maintains precise temperature setpoints through continuous monitoring and adjustment of heating elements. The module is designed for panel mounting and features a 96 x 96 x 100 mm form factor. It operates on a 24 V DC supply (24 ±10%, reverse polarity protected) with a power consumption of ≤5 W at nominal voltage. The analog input resolution is 16 bits for temperature sensors, and the control accuracy is ±0.5% FS. The sampling period is adjustable, with a default of 100 ms. It supports two independent PID loops and includes 4 digital inputs (24 V DC) and 2 relay digital outputs (2 A). Communication is via RS485 with Modbus RTU protocol. The front panel is rated IP65 per IEC 60529. Operating temperature range is -20 to 60 °C (non-condensing), storage temperature is -40 to 85 °C (in original packaging), and relative humidity is 10 to 90% (non-condensing). Materials include electronic components, PCB board, plastic housing, and metal connectors. This directory entry provides reference specifications; verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

The module continuously measures actual temperature via sensors, compares it to the desired setpoint, calculates the error, and applies PID algorithms to determine optimal control signals. These signals are then processed through PLC logic to adjust heating element power output, minimizing overshoot and maintaining stable temperature with minimal deviation. The sampling period is adjustable, and the control accuracy is ±0.5% FS. The module supports two independent PID loops, allowing simultaneous control of separate zones. Digital inputs and outputs enable integration with external switches and actuators. Communication via RS485 Modbus RTU allows remote monitoring and configuration. The front panel is IP65 rated for protection against dust and water ingress.
