2 GFX4 is a four independent loop communication, the by-now indispensable (see table in order code). controller, designed to manage electrical Profibus DP, CANopen, DeviceNet, 3 different sizes, depending on the power. Modbus RTU, Ethernet Modbus TCP. electric power managed, are available. GFX4 is a compact unit bounding The product's furnished with a standard different technological elements like: configuration, simple and quickly to GFX4 80. controller modify. Maximum contemporaneous power up to solid state relay The assignment of different functions to current transformers the outputs is very simple. Each zone could reach up to 19,2 kW. fuses-holders (option) This limit could be extend to 23,7 kW. The final result is a cost saving in terms using the smart power management . of space and cabling.

Geflex controls autonomously the four Nominal current 32A for zone loop controllers, furnishing a complete Fuse holder could be provide as an diagnostics like the loaded current, the option. control of the zones, the alarms state. A specific step by step software tool has GFX4 30. been develop in order to assist the Maximum contemporaneous power up to product configuration based on the different applications. Each zone could reach up to 7,6 kW.

Fuse holder could be provide as an Geflex dialogs with the operator terminals option. according to the most popular protocols: from the simple and efficient Modbus to, INPUTS Outupt 2 state monitor load and trip the HB alarm in O3 case of current failure or SSR in short Process analogue Outupt 3 state circuit. 4 universal process input could accept: O4 Detection of short circuit or opening of thermocouple, thermoresistance, current Outupt 4 state input probe, open loop alarm (LBA), and tension linear. interrupted load alarm (HB). The type could be choose by software By default a different meaning is Over temperature alarm and no external converting device are applicable. The software can be used to define the required.

5 POWER state of alarm outputs or a preset power level to be supplied in case of broken Digital Power is controlled with double SCR in probe. 2 digital input. anti-parallel, zero crossing switching This assures continuity of service in the The functionality could be selected within principle, with configurable proportional individual zone. a wide range including setpoint selection, cycle time. MAN/AUTO, alarm memory reset and Different load connection are available: Tuning many other. monophase, dualphases, three-phases. Self-tuning: Incorporated CT calculation of PID parameters at system art. From 1 to 4 CT control each zone and FUSES (OPTION) Auto-tuning continuous: continuous the relative alarm control is start up adjustment of PID. ( ).

6 And event-driven automatic PID. Auxiliary analogue (option) Thanks to this, you save time, wiring is parameters re-calculation 4 further analogue inputs are available, simplified, and dimensions in the panel typically for external current transformer are reduced. Special functions reading. Soft-start: power parcellization time- PROGRAMMING based Software Off: disabling of the control, OUTPUTS The Geflex modules can be programmed: outputs are turned off using GFX-OP Inputs\outputs: direct management of Output alarms configurable via software. using Winstrum tool software inputs/outputs, independently from using Industrial PC or PLC. internal firmware Heating control Simulation of four independent Geflex For each zone an heating control units. internally connected to power unit is FUNCTIONS.

Cooling control (option) Different control modes are available: The product is furnished with standard For each zone a cooling control is from a simple ON/OFF control to PID digital communication [PORT 1] used as present 4 types of outputs are available: single or double acting heat/cool (for GFX4 connection to a HMI or Industrial relay, logic, triac, continuous. cooling, simply indicate the fluid used). PC. A current transformer is furnished with Sophisticated and efficient automatic Also by a dedicated connector (10 pins). TRIAC output. tuning algorithms for control parameters it's possible to connect the actual range provide precise process control without of Gefllex.

A second standard digital communication Two relay output configurable as (PORT 2) configurable by most popular minimum and maximum alarm are Alarms protocol: available for each unit. There are 8 alarm assignable to each CANopen single canal or to all (AND / OR logic) DeviceNet and configurable as absolute, relative, Profibus DP.
