J.T.O. System NZ22-BOX - power supply
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.
Basic technical parameters:
Power supply 15 V / 0.6 A (9 W)
Two separate output relays for switching up to 230 V / 4.5 A
Two inputs for connecting the detector output signal
Status indicated by LED
Adjustment via jumpers
Selectable polarity of input signal and output relay
Possibility to use the memory function
Separate output for connection of siren or debounce button
Reversible output voltage short-circuit fuse
DIN rail mounting (4 modules) or wall mounting
The NZ22 and NZ22-BOX power supplies replace the older NZ34 and NZ34-DIN power supplies, which are no longer manufactured.
Applications:
- powering compatible detectors and transmitters
- processing output signals
- connection to a supervisory system or controlled equipment
Main features:
- Power output: 15 V / 0,6 A (9 W)
- Relay outputs: Two independent output relays for switching up to 230 V / 4,5 A
- Mounting: DIN-rail mounting (4 modules) or wall mounting
- Replacement for previous series: Power supplies NZ22 and NZ22-BOX replace the previous power-supply series NZ34 a NZ34-DIN, which is no longer manufactured.
- Mounting: DIN rail
