Simarine ST107 Digital Expansion Module for Complex Monitoring

Managing multiple fluid tanks, battery banks, and temperature zones often requires a cluttered array of individual gauges. The Simarine ST107 digital module solves this by consolidating your crucial sensor data into a single, highly capable hub. Engineered for integration into 12V and 24V marine, caravan, and RV systems, this advanced unit allows users to maintain precise oversight of fresh, grey, and black water capacities alongside electrical system health.

Comprehensive Sensor Integration

The ST107 acts as the central nerve centre for your monitoring setup. It supports highly versatile configuration options, enabling users to track up to seven individual tank levels, three battery voltages, and four separate temperature zones concurrently. The device reads signals from both voltage-drop and resistance-based sensors, providing compatibility with a wide range of standard marine and automotive senders.

Whether you need to monitor the exact voltage of an auxiliary battery bank (capable of measuring up to 75V DC) or keep an eye on engine bay temperatures using standard NTC 10kOhm sensors, this module ensures accurate, real-time data delivery to your primary display interface.

Integrated Relay for Automated Control

Beyond simple monitoring, the ST107 features a built-in monostable relay with both Normally Open (NO) and Normally Closed (NC) outputs. This allows you to configure automated actions based on sensor parameters. For instance, the relay can be programmed to trigger a visual alarm when a black water tank approaches full capacity or to automatically activate a transfer pump when fresh water levels drop below a specific threshold. This level of automation enhances system safety and convenience for off-grid travel and extended marine voyages.

Key Features

• Supports up to three voltage measuring channels (0 to 75V range with 1mV resolution)
• Accommodates four resistive measuring channels for fluid levels and temperature sensors
• Built-in relay (1A maximum operating current) for external device control
• Exceptionally low power draw, consuming just 3.5mA during standard 12V operation
• Dual digital SICOM RJ9 data ports for straightforward daisy-chain connections
• Compact 110 x 70 x 30 mm footprint for effortless installation behind bulkheads or panelling

Seamless Network Connectivity

Installation and network expansion are straightforward thanks to the dual SiCOM sockets. These ports allow the ST107 to seamlessly connect to your existing Simarine data bus, cascading with other shunts and modules without the need for complex wiring looms. Secure green screw terminal blocks ensure that your sensor and power connections remain firmly seated, even when subjected to the harsh vibrations of off-road caravan tracks or heavy marine swell.
