4 Parallel Wire 30 Channels Fixed Gas Alarm Controller HD6000
The controller is an RS485 quad-bus gas detection and warning system designed for industrial environments.
English operation interface, intuitive and easy to understand
With time display.
Alarm record can be viewed, recording the highest concentration value of the alarm and the alarm time
Display of detected gas concentration value, unit and name of gas to be detected for all channels.
Two levels of alarms can be set freely by the user
4 leakage switch values, 2 low reports, 2 high reports, also can be set freely by the user
Adjustable relay output signals, regular and pulse signals (fan is usually connected to normally open regular signal, normally open solenoid valve is usually connected to pulse signal)
Standard RS485 upload interface, can be uploaded to DCS, PLC systems and computer hosts.
Visible and audible alarm signals
Table of Contents
An audible and visual alarm sounds when the concentration exceeds the limit and the controller’s LCD display is unaffected by ambient light. It also displays the gas name and concentration value in English. The combination of internationalised icon descriptions and English descriptions is easy and convenient to use.
The controller has excellent stability, high accuracy and intelligent parameterisation. The user has full control over the type of sensors that will be connected, and with a few simple settings they can perform on-site detection and alarming. The system will automatically perform a number of alarm actions, such as audible and visual alarms, venting, tripping, etc. (depending on the user’s usage scenario), when the indicators of the specific gas to be tested on site do not meet the established standards.
Fast response, high reliability, low failure rate and easy maintenance are the advantages of the controller. Fast response time, high reliability, low failure rate and easy maintenance are the advantages of the controller. It can be widely used in petroleum, chemical, liquefied gas, coal, pharmaceutical, metallurgy, municipal and other industries, and is the ideal choice for updating and replacing gas alarms.
