GDS-OT-008 Gas Alarm Controller

Description

The GDS-0T-008 gas alarm controller adopts dual-machine dual-backplane redundancy technology, dual physical redundancy technology from power supply to field bus, and has a complete safety diagnosis mechanism. At the same time, combined with ModbusTCP technology, the system can easily and reliably connect to a variety of standard software and hardware.
The GDS-OT-008 combustible gas alarm controller has the characteristics of high reliability, high availability, fast response, large capacity, and easy maintenance. It can meet the functional safety requirements and fire certification requirements for combustible and toxic gas detection alarm systems (GDS) in different industrial fields including petroleum, chemical, energy, power generation, pharmaceuticals, metallurgy, natural gas, etc..

Functions Features

High reliability
*Dual rack redundant structure, including power supply redundancy, controller redundancy, network redundancy (optional)
*In redundant mode, the system can still operate normally in the event of a single point failure
*Typical value of redundancy switching time 90ms
*Minimum time slice for task scheduling does not exceed 100uS
*System fastest loop control cycle 50ms
Large capacity
*Single control station can add 124 10 slave stations
*The IO capacity supported by the system is greater than 1000 points
Easy to operate
*Human-machine interface HMI that meets fire certification standards, users can flexibly view real-time concentrations and various alarm records and historical records
Detectors can be flexibly turned off or on on the system human-machine interface, and switches can be controlled
