NZ34 and NZ34-DIN Power Supply

If a gas leak detection system is to work autonomously, the detectors can be supplemented with the NZ34 or NZ34-DIN power supply.

NZ34 The NZ34 power supply is designed to provide supply voltage to one or more gas detector units. The power supply also allows to process the output signal from the detectors. Relays, which are contained on the PCB, provide galvanic isolation of the detector power output.
In the power supply a delay in processing the signal from the detector can be set by the user. The delay of the relay response during the operation is used to prevent a random detector signalling, e.g. during a short exposure to flue gas in a boiler room, etc.

NZ34-DIN A warning siren or backup power supply can be connected directly to the NZ34 power supply.
The version NZ34-DIN is different in mechanical design - it is not set in a plastic box. It can be mounted on a DIN rail in a switchboard using its plastic holder. Otherwise, both versions are identical.

NZ34 or NZ34-DIN power supply are replacement for previous versions NZ23 and NZ23-DIN.
