Solid State Relay Module
Unlike electro-mechanical relays (EMR), which use coils, magnetic fields, springs, and mechanical contacts to operate and switch a supply, the Solid State Relay Module (SSR) has no moving parts and instead performs input-to-output isolation and switching functions using the electrical and optical properties of solid-state semiconductors.
SSR Solid State Relay Module, like any other electromechanical relay, provides complete electrical isolation between its input and output contacts. Its output behaves similarly to a traditional electrical switch in that it has an extremely high, nearly infinite resistance when nonconducting (open) and remarkably low resistance when conducting (closed). By using an SCR, TRIAC, or switching transistor output instead of the traditional mechanical normally open (NO) contacts, a Solid State Relay Module can be built to switch both AC and DC currents.
Key Product Features:
- Electronic components provide stable performance, so your equipment can work reliably.
- This Solid State Relay Module has a high sensitivity.
- Its expansion capacity can be used for any form of DIY project.
- It is equipped with a fuse to ensure its safety.
- Each relay has contacts that are ordinarily open and normally closed.
- Selectable through jumper relay and TTL or ground.
Specifications:
Main Functionalities:
- DC+ and DC- are used to connect the power source to the module; the voltage can be set to 5V/12V/24V. (subject to the module)
- The module trigger terminal is the CH terminal. When a trigger signal is received, the solid state relay’s output terminal switch (A, B) closes. The load will be conductive to electricity.
- The significance of high-level and low-level triggers High-level event: It is known as a PNP trigger in industrial control, and when the voltage exceeds the trigger condition before even the trigger end and the negative pole of the power supply, the relay closes.
