Overview / What Is the Maretron SIM100-01 Switch Indicator Module?
The SIM100 switch module marine is a device designed to monitor the open/close status of up to six switches, sensors, or relays onboard your boat. It integrates these signals into the NMEA 2000 network, allowing for detailed display and alert configurations on compatible multifunction displays or software like N2KView®.
Using the SIM100, marine operators can monitor critical systems such as engine room doors, smoke alarms, security motion sensors, tank level alarms, and bilge pump status. This robust solution eliminates the need for separate panel indicators or wiring nightmares by centralizing alerts into one standardized system. The SIM100-01 is also certified to withstand marine environments, making it ideal for long-term performance in saltwater and harsh conditions.
Key Features and Benefits
- Six Discrete Inputs: Monitor up to six switch signals including mechanical switches, magnetic reed sensors, or relay outputs.
- NMEA 2000 Certified: Fully compatible with other NMEA 2000 products for seamless integration.
- Custom Alerts: Configure audio/visual alerts using N2KView or display units from Garmin, Simrad, or Raymarine.
- IP67 Waterproof Housing: Built for the harshest marine environments.
- Low Power Consumption: Efficient operation without draining your onboard power system.
This module is commonly used for door sensors, high-water alarms, bilge pump activity indicators, fire detection inputs, security system triggers, and more. It ensures you’re always one step ahead of potential issues onboard.
How to Install Maretron SIM100-01 Switch Indicator Module
Installing the SIM100 switch module marine is straightforward and requires only basic tools. The module includes six input terminals to connect the switches or sensors you intend to monitor. After wiring, simply connect the unit to your NMEA 2000 backbone using a standard T-connector and drop cable.
Once connected, the device automatically transmits switch status information to your NMEA 2000 network. You can use Maretron’s USB100 or IPG100 gateway and N2KAnalyzer software to configure input names and behaviors, or use a compatible MFD (multifunction display) for direct integration and monitoring.
Common Applications for SIM100 on Boats
The Maretron SIM100-01 has a wide range of applications for recreational, commercial, and military vessels:
- Monitoring engine room doors or hatch statuses
- Connecting to fire or smoke alarms for immediate alerts
- Integrating bilge float switches to monitor pump activation
- Monitoring high-water alarms to prevent flooding
- Part of a marine security system using magnetic contact switches
By standardizing switch status across the NMEA 2000 network, boat operators can have full visibility and control over essential systems directly from the helm or even remotely when connected via IP gateways.
Maintenance Tips
Proper maintenance of your Maretron SIM100-01 Switch Indicator Module for marine ensures optimal performance and longevity:
- Regularly inspect wiring terminals for corrosion or wear, especially in saltwater environments.
- Use marine-grade connectors and waterproofing materials during installation.
- Update firmware periodically using Maretron N2KAnalyzer for enhanced performance and bug fixes.
- Verify input signals are functioning correctly by conducting routine system tests via your MFD or N2KView.
Maintenance is minimal thanks to the device’s robust build, but scheduled inspections during annual servicing will help prevent data loss or system faults.
Expert Advice and Pro Recommendations
Professionals in the marine industry regard the SIM100 switch module marine as an essential tool in both new builds and retrofit projects. It’s often the go-to solution for enhancing vessel monitoring systems without increasing wiring complexity.
To maximize the SIM100’s potential, integrate it with the Maretron N2KView system. This enables comprehensive control and visual monitoring from any connected device – onboard or ashore. Consider pairing it with Maretron’s SSC300 for compass data, or TMP100 for temperature monitoring to build a full vessel monitoring suite.

Detailed FAQ Section
What is the Maretron SIM100-01 used for?
The Maretron SIM100-01 is a marine-grade switch indicator module designed to bring up to six discrete switch or sensor signals onto the NMEA 2000 network. This allows these inputs to be displayed, logged, and alarmed via compatible displays or software. Boaters use it to monitor door switches, smoke detectors, bilge activity, high-water sensors, and many other on/off devices. With this module, real-time visibility into critical systems becomes part of your vessel’s electronic dashboard, improving safety and situational awareness.
How do I connect switches to the SIM100 module?
Each of the six input terminals on the SIM100 module can accept contact closures or open/close switches. These are typically dry contacts, such as float switches, reed sensors, or relay outputs. Simply connect one wire to the common terminal and the other to the input terminal. Once wired, you connect the module to your NMEA 2000 backbone using a drop cable. After configuration using Maretron’s N2KAnalyzer or via compatible MFDs, your boat’s switch status will be visible across your NMEA 2000 system.
Can I use the SIM100 with non-Maretron systems?
Yes, the SIM100 is NMEA 2000-certified and compatible with most marine electronics brands that support discrete input PGNs. Displays from Raymarine, Garmin, Simrad, and others will detect and visualize switch states transmitted by the SIM100. For best results and full customization, pairing it with Maretron’s N2KView software is recommended. The modular design ensures seamless integration into a multi-brand network, making it highly versatile for various vessel configurations.
What is the typical lifespan of the Maretron SIM100-01?
