Technical details and manufacturing context for PID Control Module

Definition

The PID Control Module is a critical component within Power Controller (SSR/PID) systems that continuously calculates an error value as the difference between a desired setpoint and a measured process variable, then applies correction based on proportional, integral, and derivative terms to achieve and maintain precise temperature control in industrial heating applications. The module receives temperature feedback from sensors, compares it to the setpoint, calculates the PID algorithm output, and sends control signals to solid-state relays (SSRs) to adjust power delivery to heating elements, minimizing overshoot and maintaining stable temperatures. It is designed for DIN rail mounting and operates from a 24 V DC supply (24 ±10%, reverse polarity protected) with a power consumption of ≤5 W at nominal supply. Control accuracy is ±0.5% of full scale, and the sampling period is adjustable from 100 to 500 ms. PID parameters are adjustable with proportional range 0.1–100, integral time 0–3600 s, and derivative time 0–3600 s. The module accepts a 4–20 mA input signal (also 0–10 V DC) and provides an isolated 4–20 mA output. It operates in non-condensing conditions over -40 to 85 °C, with storage from -40 to 105 °C, and relative humidity 5–95% non-condensing. Ingress protection is IP54–IP65 depending on housing, per IEC 60529. Dimensions are 100×75×25 mm (W×H×D), and weight is ≤200 g without packaging. The module is constructed with a printed circuit board, microcontroller/processor, and electronic components (resistors, capacitors, ICs). For procurement, verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The module receives temperature feedback from sensors, compares it to the setpoint, calculates the PID algorithm output, and sends control signals to solid-state relays (SSRs) to adjust power delivery to heating elements, minimizing overshoot and maintaining stable temperatures. The PID algorithm continuously computes the error and applies proportional, integral, and derivative corrections to achieve precise control.
