Solid State Relay Unit (BT136S)
SSR (Solid State Relay) Unit relays are a type of relay that differ from traditional electromagnetic relays in several ways. One significant difference is their extended switching life, which is much longer compared to electromagnetic relays. This longevity is achieved because SSRs utilize power semiconductor devices for switching instead of mechanical contacts.
SSR Unit incorporates the MOC3043M optocoupler isolation and zero-crossing detection. The MOC3043M is an optically isolated triac driver that provides electrical isolation between the control circuitry and the output power circuit. The zero-crossing detection feature ensures that the switching of the SSR occurs at the point of zero voltage crossing, minimizing electrical noise and reducing stress on the connected devices.
SSR Unit supports a control signal input range of 3.3-5V DC, making it compatible with microcontrollers and other digital control systems. The control input allows users to switch the output power of a single-phase 220-250V AC source.
SSR Units are known for their fast switching speed, typically in the range of microseconds. This rapid on/off capability is enabled by the power semiconductor devices used within the SSR. Additionally, SSR Units often include built-in over-current protection mechanisms to safeguard against excessive current flow.
These characteristics make SSR Units suitable for applications that require frequent switching and fast response times. They are widely used in various industries, including lighting control systems, CNC machine tools, automation, and other applications where precise control and quick switching are necessary.
Note:
1. Please be careful when using high voltage AC loads, and do not operate with electricity.
2. This relay is for AC loads only.
