Good quality China Multi Channel Workshop Safety Control Alarm System Gas Detector Controller (8 channels)

Short Description:

The 19” cabinet standard 3U panel-mounted all-metal structure can prevent EMI/RFI interference. Due to an independent plug-in card design, optional channel cards, master control cards and power supply cards can be used as required to set up a gas monitoring system with up to 1,000 point locations;

The master control card is characterized by LCD Chinese display and character menu operation. It can monitor the system’s concentration, alarm and failure statuses. It can also be used to set and search various parameters. It can set system time, range (%LEL, ppm and %VOL), three alarm types, alarm concentration, password, and operating authorization and search up to 999 alarm and failure records and 100 startup/shutdown records;

ACTION gas detectors are OEM & ODM supported and true mature devices, long-tested in millions of projects domestic and overseas since 1998! Don't hesitant to leave your any inquiry here!

Major Features

● The 19” cabinet standard 3U panel-mounted all-metal structure can prevent EMI/RFI interference. Due to an independent plug-in card design, optional channel cards, master control cards and power supply cards can be used as required to set up a gas monitoring system with up to 1,000 point locations;

● The master control card is characterized by LCD Chinese display and character menu operation. It can monitor the system’s concentration, alarm and failure statuses. It can also be used to set and search various parameters. It can set system time, range (%LEL, ppm and %VOL), three alarm types, alarm concentration, password, and operating authorization and search up to 999 alarm and failure records and 100 startup/shutdown records;

● The master control card’s RS485 bus communication interface, equipped with a standard MODBUS protocol, can communicate with the host control systems and connect fire and gas systems to improve the system integration level;

● Channel cards can receive 4-20mA signal or switching value signal input and be connected with various devices, including combustible gas detectors, toxic and hazardous gas detectors, oxygen detectors, flame detectors, smoke/heat detectors and manual alarming buttons, etc.;

● With a LED display accuracy of 0.000-9999, channel cards can monitor external equipment’s concentration, alarm and failure statuses on a real-time basis and communicate with the master control card. Channel cards can also work independently and be used to set parameters of detectors. Thus, failure of the master control card or failure of other channel cards will not have an impact on channel cards’ gas monitoring;

● Channel cards’ multiple output types are applicable to linkage of various on-site external control devices, good for integration of the host control system;

● Power supply cards supply DC24V power supply to internal devices of the host computer and on-site devices (in case of higher capacity, use special-purpose firefighting power supply).
