The Macurco 12-Series are line voltage powered (100-240VAC), dual relay gas
detector, controller and transducers. The 12-Series utilizes an internal switching
power supply that is capable of using line voltage between 100 and 240VAC and
50-60Hz. The 12-Series have selectable 4-20mA output, buzzer and digital display
options. It is an electronic detection system used to measure the concentration of
various gases and provide feedback and automatic control to help reduce gas
concentrations in parking garages, warehouses or other commercial applications.
