DUOmaster CO/LPG H
Detektor tlenku węgla CO i propanu-butanu LPG
The "DUOmaster CO/LPG H-B" dual-gas detector is designed for use in stationary carbon monoxide (CO) and propane-butane (LPG) detection systems outside potentially explosive atmospheres. Typical applications for the "DUOmaster CO/LPG H-B" detector include detection systems in garages and underground car parks. The housing (through the use of cable feed-throughs) is suitable for installation in flush-mounted wiring systems. The "DUOmaster CO/LPG H-B" detector is designed for cooperation with control panels or controllers via the RS485 bus. Wide range of supply voltage - nominal 24 V DC, possible 12-28 V DC. Digital output - RS485 connection, Modbus RTU protocol, addressable detector.
Sensors used :
- carbon monoxide CO : electrochemical, (selective, two-threshold measurement or detection, alarm thresholds : 40/100ppm, measuring range 0...500ppm)
- propane-butane (LPG) : solid-state (non-selective, alarm thresholds : 10/30%DGW)
Visual indication on the detector for power supply, exceeding of alarm thresholds, failure .
The detector consists of two modules: the main (CO) module and the LPG module connected by a cable (flush mounted).
Main module (CO) - PS plastic casing, cable bushings - 3 pcs. (power supply, RS485 output, connection to LPG module).
LPG module - PS plastic housing, cable grommet - 1 pc. (for connection with main module)
Versions :
- DUOmaster CO/LPG H-B - electrochemical CO sensor, semiconductor LPG sensor, RS485 output with Modbus RTU protocol, for flush wiring
