Si Marine ST107 Tank Module

The ST107 digital tank module is a highly versatile module. Its main purpose is to measure water, fuel, or other liquid levels (tank monitoring), but you can also use it to measure voltage or temperature.

The ST107 brings 4 resistance and 3 voltage inputs to the system. With them, you can monitor:

– resistance inputs: analog resistance type tank level sensors or temperatures
– voltage inputs: voltage-only batteries (any battery type except lithium), analog voltage type tank level sensors, and custom user sensors

The resistance inputs require sensors ranging from 0 ohms to 65,000 Ohms, and the voltage inputs sensors ranging from 0 V to 75 V. You can connect any tank-level sensor that operates in this range or anything in between.

The compatible temperature sensors are:

– NTC 10k, with which our system can measure temperatures down to -13°C
– NTC 5k, with which our system can measure temperatures down to -20°C
– NTC 1k, with which our system can measure temperatures down to -40°C

One of the special features of this module is a built-in, programmable alarm signal relay, which you can configure to output a signal of 1 amp if an alarm is triggered.
