How can I design a system that would allow me to put multiple receivers on a single 4-20mA current loop? Assume that I have design control over only one of the receivers.
Sensor:
- Loop powered (2-wire)
- Supply voltage: 12-28VDC
- Max Load: 250 Ohms @ 12VDC (500 Ohms @ 24VDC)
Current Receiver Design:
- 250 Ohm resistor to ground
- Loop power supply ground is connected to ADC ground
