The NORIS N3000-IMC/L serves as a high-performance distributed I/O and measuring controller designed for the demanding requirements of marine engine monitoring and alarm systems. It excels in processing a variety of sensor inputs—including PT100 temperature sensors, 4-20mA pressure transmitters, and binary switch contacts—providing digitized data over a redundant CAN bus network to the central NORIMOS monitoring station for real-time propulsion and auxiliary machinery oversight.

Model Comparisons
The N3000-IMC/L is the large-format version of the I/O series, offering 16 inputs compared to the 8 inputs found on the compact N3000-IMC/S (Small) model. While the “S” model is intended for localized sensor clusters, the “L” version (PAAE045082 equivalent logic) acts as a high-density hub for comprehensive engine room data acquisition. Compared to the N3000-DMP (Display Module), the IMC/L is a blind processing unit, focusing entirely on signal conversion and threshold monitoring without an integrated screen, which allows for a more ruggedized, vibration-resistant internal hardware design.
Operating Tips
- Termination Resistance: When the N3000-IMC/L is the last physical device on the CAN bus branch, ensure the internal 120-ohm termination resistor is activated via the onboard jumper to prevent data packet collisions.
- Sensor Shielding: For PT100 and analog inputs, terminate the cable shields at the designated “S” terminals on the module; failure to do so in the high-EMI environment of a marine engine room will result in “flickering” alarm values.
- Redundant Power: Utilize both power input terminals (Supply 1 and Supply 2) from independent 24V DC battery banks to maintain monitoring capabilities during a primary generator failure or “Black Out” condition.
