PC817 Optocoupler Isolation Board
Key Product Features:
- The Optocoupler Isolation Board can do low-level driving as well as voltage conversion.
- The MCU’s IO voltage can be graded using this module to achieve an isolated drive between various levels of voltage.
- By selecting the jumper cap of each channel, you can get individual control over whether it is coupled with the input.
- The jumper cap is shorted so that the output terminal’s negative terminal is linked to the power supply’s negative pole.
- Each channel has its own power indication, which may be directly controlled by the MCU’s IO port.
- The input terminal is 5V high, and a current of 3-5MA can be driven.
- MCU output power to power the motor when an inductive device, such as a motor, is isolated, anti-interference safeguards the MCU’s circuit.
- The single-chip microcomputer’s output level is low, and the driving power of the driven module is high. For example, for level matching, some PLC input should have 24V voltage and can be converted by this module.
- The input signal of the inverter can be inverted.
Applications:
- Used for high voltage detection, such as when a sensor’s output signal level is 12V. The single chip has a voltage of 5V.
- This module can be used to detect isolation.
Specifications:
- Voltage: 3 – 5v
- Adaptive: PLC 24 Level
- Output TTL Level Can Use: SCM to Test
