NZ424 and NZ424-DIN Power Supply
If a gas leak detection system based on 4-20 mA current loop is to work autonomously, the detectors can be supplemented with the NZ424 or NZ424-DIN power supply.
The NZ424 power supply is designed to provide supply voltage to one or
maximum 4 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. User can set up number of connected sensors and
level for every output relay.
The version NZ424-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.
