PROFILE
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 communi-
cation, 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.

INPUTS
Process analogue
4 universal process input could accept:
thermocouple, thermoresistance, current
and tension linear.
The type could be choose by software
and no external converting device are
required.
Digital
2 digital input.
The functionality could be selected within
a wide range including setpoint selection,
MAN/AUTO, alarm memory reset and
many other.
Incorporated CT
From 1 to 4 CT control each zone and the
relative alarm control is start up (HB..).
Auxiliary analogue (option)
4 further analogue inputs are available,
typically for external current transformer
reading.
OUTPUTS
Output alarms configurable via software.
