Main Application

Electric heating system and temperature control equipment: Modern electric heating temperature control systems are evolving towards intelligence, networking, and green efficiency.In terms of specific applications in this field, intelligent solid state relays demonstrate wide adaptability, including industrial electric furnaces, ovens, injection molding machine temperature control systems, hot presses, etc. Intelligent solid state relays can achieve precise temperature adjusting and switch controlling for resistive heating elements. Moreover, temperature control modules combined with Internet of Things technology can realize real-time remote monitoring of equipment status and energy efficiency optimization, contributing to the development of Industry 4.0 and green manufacturing.

The intelligent solid state relay has evolved from a simple “power switch” to a “smart control core”. It ensures product quality through precise temperature control and enables predictive maintenance through data-driven capabilities. It is a key component that drives the intelligence, efficiency, and high reliability of rubber and plastic equipment. For instance, in the plastic industry, the temperature control of the barrel and mold of injection molding machines is crucial for forming accuracy. By using the intelligent solid state relay system, the stability of melt flow and the cooling and shaping process can be ensured.

In the field of material processing, intelligent solid state relays assist industrial ovens by relying on a forced hot air circulation system and precise temperature control, ensuring that the temperature uniformity within the chamber reaches ±1%℃, thus meeting the drying or heat treatment requirements for various materials.

Characteristics of Intelligent Solid State Relay

Miniaturization:

A more compact design, reducing the volume by 30% compared to the previous generation.

Intelligent Design: Dual LED indicators display "Operational" and "Fault" statuses.

Initial/Standby: Only the red light is on (power is supplied to the load end, but no control signal is present).
Normal operation: Green light is on, red light is off.
Normal shutdown: Green light is off, red light is on.
Fault status: Both lights are on simultaneously, or neither light is on.
