G-LINK MASTER STATION
The G-LINK is a value-added digital communication system that centrally controls a variety of instruments and sensors, including valve actuators.
- The system connects the sensors and actuators with an optical fiber loop, and allows remote control and monitoring.
- The G-Link is a highly flexible safe, reliable, large capacity, high speed, economical optical communication system.
- It can be structured to accomplish the desired combination of operations, such as opening and closing valves and gates.
- One loop is capable of controlling up to 127 field devices.
- The system has abundant functions including position indicators, monitors, alarms etc.
- Dual circuits, double masters, and a loop back function can be used to ensure tolerance against faults.
- A function to convert analog signals into digital ones is provided as an option.
The FFI system uses an optical fiber to control all sorts of instruments and valve actuators.
- Optical signals from the master station can travel through the optical star coupler which distributes and collects optical signals from field devices, and send them to the host computer. Transmission between the host computer and the optical star coupler can be made redundant.
- Control of field devices is possible by way of the master station.
- The maser station is connected to the control panel via analog, digital, parallel or serial signals.
- 3 types of Limitorque are provided for use with the FFI system.
- 32 seperate field devices can be connected to the master station.
* The FFI is a Fiber Optic field instrumentation system developed by Fuji Electronics Co.,Ltd.
Mounting Rack of 16 TWC Central units
TWC(Two Wire Control System)
This system controls the field actuator and the central unit with two wires (1:1 communication control).
By using CPU and secure hardware, you can answer back through communication control through two wires by opening/ closing the control.
