UNIVERSAL MULTILOOP CONTROLLER SCALABLE AND EFFICIENT PID CONTROL Gefran’s 2850T – 3850T series of controllers provides multiloop PID control solutions with advanced control functions and simple configuration. The controllers use a cutting-edge PID control algorithm for high performance and reliable process control. Each PID can be easily configured as a single loop controller, connected to the profile generator, as a cascade controller or ratio controller. Compliance with AMS2750 and CQI-9 standards, allows to use Multifunction series in Aerospace and Automotive applications, as a temperature...

Heat treatment requires change of the setpoint over time for the various PID controls. The 2850T/3850T series meets this requirement by configuring profile generators. The profile generator provides simple configuration of setpoint profiles and programming of assigned events. It can be programmed online directly on the controller or offline with a dedicated editor in GF_ eXpress configuration tool. A setpoint generator program consists of: - Segments: Up to 4 setpoints that follow the configured profile. - Events: series of conditions or commands assigned to each segment. - Logic: list of logic...

DATALOGGER E BATCH REPORT MULTICHANNEL GRAPHIC RECORDER... The 2850T/3850T series combines process data storage capacity with secure and easy data availability. All in a compact controller with a brilliant colour touchscreen. Data can be displayed in graphic trend mode, with cursor for quick and easy reading of a series of values over a given time. All process data is stored securely on the controller’s memory and can be saved in standard (.CSV) or encrypted format and exported via USB or Ethernet network. TREND / BATCH REPORTS The Trend / batch report option lets you archive process data, In/...

...REMOTE DATA ARCHIVING AND MANAGEMENT ETHERNET TCP/IP PC REPORT UTILITY The 2850T/3850T series has a dedicated PC utility that manages the datalog files and batch reports archived in the controller. The utility lets you automatically (with manual command or configurable time interval) copy and delete files archived in the controller from a PC linked in Ethernet. Data archived on the PC can be displayed in graphic Trend or tabular (Excel) format. They can also be exported in standard .CSV or .PDF format. TIME SYNCHRONIZATION (SNTP) For precise archiving of the date/time of datalog archive data,...

A SINGLE CONFIGURATION TOOL GF_EXPRESS GF_eXpress is the software configuration suite for all Gefran devices. A series of dedicated graphic interfaces, allows a clear and simple controller configuration. ETHERNET TCP/IP CONFIGURATION PARAMETERS Direct access to all configuration parameters in a simple and immediate list. An integrated monitor window, in oscilloscope style, helps control tuning operations. CONTROL LOGICS A fully graphic interface with On-line test functions is included for control logic configuration to quickly and securely check the control or mathematics function sequence. CUSTOM...

...AND ALL AT YOUR FINGERTIPS CONFIGURATION PARAMETERS Direct access from touch interface to all parameters with 3-level password protection. This is the Gefran technology to directly set up all logic and mathematics functions from the tool. GETview is the function that lets users build manmachine interface pages directly from the touch-screen.

ALSO REMOTELY FACTORY INTEGRATION AND SYSTEM DIAGNOSTICS 2850T/3850T series controllers are ready for connection to centralized acquisition or control systems such as HMI or DCS for integration in factory management. This is done by means of an Ethernet TCP/IP connection based on standard Modbus TCP protocol. You can also access the system remotely by PC, tablet or smartphone with the standard VNC service. In case of failure, the controllers provide clear diagnostics, such as fault, interrupted load, off-scale, etc. Built-in FTP Client function enables automatic, secured and remote storage over...

MODEL 3850T-XX-4 3850T-XX-8 Analog (universal) Ins

APPLICATION EXAMPLES AUTOCLAVE STERILIZATION Autoclave sterilization applications require PID multiloop functions, time base control programs, and logging of production data. They generally require 2 PID loops (Temperature and Pressure) linked to a setpoint profile generator. INTERNAL PRESSURE INTERNAL TEMPERATURE FOOD TEMPERATURE PRESSURE CONTROL HEATING CONTROL The main characteristics of these applications are the archiving of process values during the sterilization cycle and the calculation of F0, i.e., the time equivalent to sterilization temperature. FO calculation lets you automatically...
