The multiple Relay Board is an easy interface solution, to use in combination with NisshaFiS Gas sensor module (FiS3000 series), that commutate the signal from Open Collector (Gas Module) to Dry contact. It's goals are to give back alarm outputs available for mostly HVAC central unit and also to be a simple complete solution in those small systems where the "classical" gas detection systems on market are too excessive. Moreover the FiS3000 gas sensor module is precalibrated, cheap and robust component with Alarm, Prealarm and Malfunction output which doesn't requeire calibration , Thanks to the easy interface, low mantenance and low price it is a highly useful tool to own a Gas Leakage device.
The GVZ Gas leakage relays board is a flexible and easy solution used to control and commute the Open collector signal (from FiS3000 gas sensors) in a dry contact solving the most common requests of the markets. It is also the perfect solution to have a gas leakage system where the dimension and price of the final device not allow the installation of a complex system.
