The Offshore Systems’ 4521 4 Channel Temperature Module monitors up to 4 type K thermocouples and reports their temperature over the NMEA2000® network.
These thermocouples can include our rugged engine room temperature sensor 4525, Our Cabin air temperature sensor 4522, our liquid temperature sensor 4523 and our ring bolt temperature sensor 4524. The unit will also work with standard type k temperature sensors that are user supplied.
The unit has user configurable temperature source information for each channel and a red warning LED that is lit if the sensor is damage or improperly connected.
The connections from the thermocouples to the unit are made by the boat builder preferred Wago cage clamp terminals.
The unit can be either panel mounted or DIN rail mounted using the clips supplied. It comes with a detailed user manual and is certified to work with NMEA2000®.
The 4521 NMEA2000® 4 Channel Temperature Module is an important part of our Integrated Alarm, Display and Control System.
