1. Introduction
The SCQ25T digital shunt module is Simarine’s most versatile module. It can
be used to measure voltages, currents, liquid levels
and temperatures.
SCQ25T has 4x 25 A integrated shunts, capable of measuring voltage up to
35 V DC and continuous current up to 25 A on
each shunt.
SCQ25T can measure temperature or liquid level such as water, fuel or any
other liquid. It comes with 4 integrated
resistance inputs operating from 0 ohm - 65 kohm and 3 integrated voltage
inputs, operating from 0 V - 32 V.
You can connect any tank or temperature sensor operating in this range.
SCQ25T also features a configurable alarm contact, which fires on specific
alarms. It can handle a maximum current 1A on maximum 30V DC. The alarm
is configurable via PICO’s device menu or PICO's mobile app menu.

2. Safety
DISCLAIMER: 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 the area with 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.
