Our product range includes a wide range of gfx-4 4 4 loop modular power controller, autonics digital thyristor power controller, single phase digital thyristor power controller, gpc advanced power controller and gtf power controller.
GFX4 is a four independent loop controller, designed to manage electrical power. GFX4 is a compact unit bounding different technological elements like: • controller • solid state relay • current transformers • fuses-holders (option) The final result is a cost saving in terms of space and cabling. GFX4 consisting of: • power management unit • analog and digital inputs, • analog and digital outputs • standard digital communication • integrated solid state relays • fuses-holder (option) Geflex controls autonomously the four loop controllers, furnishing a complete diagnostics like the loaded current, the control of the zones, the alarms state. A specific step by step software tool has been develop in order to assist the product configuration based on the different applications. Communication with the outside is of primary importance. Geflex dialogs with the operator terminals according to the most popular protocols: from the simple and efficient Modbus to, by a second optional fieldbus communication, the by-now indispensable Profibus DP, CANopen, DeviceNet, Modbus RTU, Ethernet Modbus TCP, Ethernet IP, EtherCAT, ProfiNET. The product’s furnished with a standard configuration, simple and quickly to modify. The assignment of different functions to the outputs is very simple.
