1/1 Control Units EcoAlpa Product code: PW-054-X EcoAlpa is a two-channel control unit designed to work with gas detectors with a 4 – 20 mA interface – it is responsible for visualizing the operation of the entire Gas Safety System and for developing appropriate output signals. See full description Functionalities: Certificates: Product description Technical details The EcoAlpa Control Unit is a dual port control device designed for collaboration with gas detectors communicating by means of 4..20 mA control signals. It has analog outputs to connect a sound and optic warning device and digital lines for transmission of the system status information. In addition, the control unit can be integrated with a superior automation system, for instance BMS. The EcoAlpa unit is available in several manufacturing options that are able to perform selected functionalities of the system, such as control for the gas shutoff valve (various gas types) or switching the system over to the backup power supply voltage to continue operation of the system when the mains voltage disappears. The table below summarizes details of the types and options of the control unit: Lp.
