Looking for an Electronics Engineer
We need a circuit designed to interface with an ESP32. The circuit should be capable of transmitting and receiving logic 1 and logic 0 commands via a two-wire current loop interface. It must support full-duplex communication, meaning it should also be able to receive responses.
Logic Explanation:
Based on the attached specifications:
1. Logic 0 ("Space"):
Current: Between 0 mA (Minimum) and 2 mA (Maximum).
2. Logic 1 ("Mark"):
Current: Between 42.75 mA (Minimum) and 47.25 mA (Maximum).
The current loop operates at a nominal 45 mA ±5%. The voltage for the open-loop supply must be between 12V DC (Minimum) and 42V DC (Maximum).
Requirements:
The designed circuit must handle current regulation for transmitting the appropriate logic levels (0 and 1).
It should interface seamlessly with an ESP32's GPIO pins for sending and receiving signals.
Protection against exceeding the voltage limit is essential.
Ensure compatibility with industrial-grade operating temperatures (0°C to 60°C).
If you're an experienced electronics engineer with expertise in current loop interfaces and ESP32 applications, please get in touch.
