OIC-406
Temperature & Humidity sensor.
The OIC-406 has NMEA output. Connecting the basic node to OMC-183-ML is possible
by using NMEA1 IN or NMEA2 IN.

OMC-406
Temperature & Humidity sensor
.
The old OMC-406 is a less accurate sensor, and got two 4-20mA analog outputs. These
signals can be connected to OMC-183-ML by using two of the analog current input ports
for example current inputs 2 & 3:
Recommended cable: shielded 2x2x0,75mm2 twisted pair
