The input interface adopts photoelectric coupling circuit, which can greatly reduce the electromagnetic interference, and the input response time is generally less than 2 ms.
The output adopts photoelectric isolation to reduce electromagnetic interference and increase stability.
Relay output type
The relay output is suitable for low-frequency high-power load (AC / DC power supply output), and the response time is on → off10ms, off → on8ms.
Thyristor output type
The thyristor output is suitable for high frequency and high power load (AC power supply output), and the response time is several hundred μ s ~ several Ms.
Transistor output type
Transistor output is suitable for high frequency low power load (DC power supply output), the response time is hundreds of μ s ~ tens of μ s.
