product details
The GD3000-2 gas alarm controller adopts dual machine dual backplane redundancy technology, with dual physical redundancy technology used from the power supply to the fieldbus, and has a complete safety diagnostic mechanism. At the same time, combined with Modbus TCP technology, the system can easily and reliably connect multiple standard software and hardware.
The GDS3000-2 combustible gas alarm controller has the characteristics of high reliability, high availability, fast response, large capacity, and easy maintenance. Can meet the functional safety requirements and fire certification requirements of different industrial fields including petroleum, chemical, energy, power generation, pharmaceuticals, metallurgy, natural gas, etc. for combustible and toxic gas detection and alarm systems (GDS) 0
The main function of the GDS3000-2 combustible and toxic gas data online monitoring and detection system is to centrally monitor and manage the collected data information, receive and process the collected data information, upload all data information to the GDS upper computer configuration software, and the GDS upper computer presents real-time display of data and alarm status at each point, real-time curve depicting the data changes at each point, real-time display of historical records and viewing and printing, and real-time display of the current working status of each point, that is, automatically counting the normal number, alarm number, and fault number; According to the low and high reports reflected by the GDS system, the emergency plan is activated, and other devices such as fans, alarm lights, and fire alarm systems are linked to enable modes. Sound and light alarms and video linkage can be provided, and sent to relevant responsible persons through multiple methods such as mobile SMS, SMS, phone reminders, and email.
Product features:
◆reliability
◆Adopting a dual rack redundancy structure, including power redundancy, controller redundancy, and network redundancy.
◆In redundant mode, the system can still operate normally in the event of a single point of failure
◆The typical value of redundant switching time is 90ms
◆The minimum time slot for task scheduling shall not exceed 100us.
◆The fastest loop control cycle of the system is 50ms
Large capacity
◆A single control station can add 124 IO slave stations.
◆The system supports an IO capacity greater than 1000 points.
Reliability
◆Each detector is equipped with distributed power on/off and short-circuit protection function. If any detector experiences a power short circuit, it will not affect the normal operation of other detectors, and will automatically determine whether the detector is disconnected or short circuited and issue an alarm.
◆Not only can it determine whether the switch is open or closed, but it can also automatically determine whether the switch is disconnected.
◆Automatically determine whether the sensor has fallen off and issue a fault alarm
Easy to operate
◆HMII human-machine interface that meets fire certification standards, allowing users to flexibly view real-time concentration, various alarm records, and historical records
◆The detector can be flexibly turned on or off on the system human-machine interface, and the switch can be controlled
