Maretron Switch Indicator Module SIM100 – SIM100-01

Description

Maretron Switch Indicator Module – SIM100 (SIM100-01)

Enhance your vessel’s digital monitoring and control capabilities with the Maretron Switch Indicator Module SIM100 (SIM100-01). This versatile NMEA 2000®-ready module monitors the status of up to eight discrete electrical switches — such as bilge pumps, lights, sensors, door/hood contacts, and other on/off circuits — and reports their states directly to your NMEA 2000® network.

Designed for reliable marine performance, the SIM100 seamlessly integrates with Maretron displays, chartplotters, and vessel monitoring software so you can view switch status in real time at the helm or from multiple networked stations. Whether you’re tracking bilge pump activation, monitoring hatch or door positions, or adding auxiliary system indicators, this module turns simple switch closures into meaningful system data.

Built with a rugged, marine-ready enclosure and sealed NMEA 2000® connectors, the SIM100 is engineered for corrosion resistance and long service life in the harsh offshore environment. Easy to install and expand, this module helps simplify wiring while centralizing switch data on your vessel’s network backbone.

Key Performance Features

• Six-Channel Monitoring: A single module can track six independent devices, providing real-time “on/off” or “open/closed” status for various critical systems.

• Versatile Switch Support: It works with a wide range of devices, including bilge pump float switches, magnetic security sensors, smoke detectors, and pressure switches.

• Programmable Logic: You can configure each channel to be “Normally Open” or “Normally Closed,” and even set up alarm thresholds so that your MFD alerts you immediately if a switch changes state.

• Network Integration: Status data is broadcast over the NMEA 2000 bus, making it visible on any compatible display, such as a Maretron DSM570 or via remote monitoring software.

• Compact & Rugged: The unit is designed for the marine environment with an IP64 rating (splash-resistant) and a small footprint for easy installation behind the dash or in an electronics locker.
