1Introduction
Simarine’s ST107 Digital tank module is a highly versatile module. Its main purpose is to measure any liquid level. But it can
be used to measure voltage, current or temperature.
ST107 Digital tank module can measure liquid level such as water, waste water, fuel or any other liquid. It comes with 4
integrated resistance sensing inputs operating from 0 ohm - 65 kohm and 3 integrated voltage sensing inputs, operating from 0
V - 35 V DC. You can connect any tank or temperature sensor operating in this range.
ST107 also features a configurable alarm contact, which fires on specific alarms. It can handle max. current 1A on max. 30 V
DC. The alarm is configurable via PICO’s menu.
2Safety
Installation of Simarine electronics should be made by electrical specialists with proper safety equipment. When working with
batteries you should wear protective clothing and eye protection.
CAUTION: Batteries contain acid, a corrosive, colorless liquid that will burn your eyes, skin and clothing. Should the acid
come in contact with eyes, skin or clothing, wash it immediately with soap under fresh water for at least 15 minutes, and seek
medical support immediately.
CAUTION: Do NOT connect anything to a damaged battery. It could heat up, catch fire or explode.
CAUTION: Lead-acid Batteries can generate explosive gases during operation. Never smoke, allow flames or sparks near the
battery. Make sure to keep sufficient ventilation around the battery.
CAUTION: When working with a battery remove all personal metal items like watches, rings, necklaces and bracelets. Metal
items in contact with the battery terminals might cause a short circuit with a very high electric current, which may heat up and
melt nearby objects and cause severe burns.
