5.6 Installing of Multiple Sensors via RS485

The distance between the sensor and a computer can be up to 1200 m (4000 ft.) via RS485 interface. This allows ample distance from the harsh environment where the sensing head is mounted to a control room or pulpit where the computer is located.

The RS232/485 adapter comes with a power supply:

RAYMINCONV2

for 230 VAC

RAYMINCONV1

for 110 VAC

Connect the signal line as shown:
