The NZ22 power supply is used to power one or more gas detectors. The NZ22 power supply can also process the output signal from the detectors. Two relays, which are included on the electronics board of the power supply, provide power potential-free isolation of the detectors' output and ensure easy connection to the parent system or controlled actuators (such as valves, fans, beacons...). Each relay is controlled independently according to the selected setting. The power supply allows you to set additional functions in signal processing, such as input inversion selection, memory function, etc...
Type NZ22-BOX is designed for direct wall mounting. It consists of the NZ22 source placed in a small junction box, which also incorporates a deblocking button and siren.
