Please Note: Updated Monday, May 26, 2020  We are open for business as usual. Well, mostly usual. We hold and ship inventory locally as well as directly from manufacturers and from some marine distributors. We are doing our best to reflect inventory that is actually available, but inventory updates are slower than usual due to the changing work situations for all business. Additionally, we now have started to see longer than normal backorders from manufacturers. We recommend that if you need a product not to wait until the last minute to order, as inventory may be gone for a substantial period of time once they go on backorder. International orders may also take longer than normal to ship.

Oceanic Systems NMEA2000® 4 – 20mA Pressure Adaptor - 4601

Special Order Item - Will generally ship to you in four to six business days.

Oceanic Systems NMEA2000® 4 – 20mA Pressure Adaptor - 4601

The Oceanic Systems’ NMEA2000® 4601 4 – 20mA Pressure Adaptor is designed to monitor any 4 – 20mA pressure source including Atmospheric, Water, Steam, Compressed Air, Hydraulic, Oil & Fuel on the NMEA2000® network.

This unit is designed to operate in a protected marine environment such as an engine room. It provides a standard NMEA2000® pressure PGN130314 over the network and is an important part of our complete NMEA2000® Monitoring and Digital Switching System.

It is fully waterproof to IP67 and ruggedly constructed for years of reliable and accurate service.

The unit comes with a detailed User Manual and is certified to the NMEA2000® network standard.

  • Convert 4 – 20mA pressure input to digital value with ± 2% FSD accuracy
  • User selectable pressure range
  • User selectable pressure source
  • Faulty sensor/connection detection (under or over current)
  • No complicated menu setups required
