New all-in-one multi-zone temperature controller and display
Gefran's new GF_PROMER (Gefran Programmer) combines a time variable four-loop setpoint temperature controller with a graphic trend and bargraph display in a single programmable touchscreen device with on-board memory. Designed to simplify temperature control for applications such as thermal treatment furnaces, climatic chambers and autoclave driers, the GF_PROMER suits a wide range of voltage and current sensor input types when used with GEFLEX series controllers, connected to GF_VEDO panels with high-speed Modbus RTU communication, or by installing GILOGIK II series analogue and digital I/O modules directly on the backplane. A comprehensive and multiple selection of setpoint profile functions includes on/off, PD, PID and heat/cool with double independent PID.
The GF_PROMER is available in 3.5inch and 5.7inch high-resolution touchscreen versions with a 1/4 VGA IP65 display. Programming is menu-driven and designed for guided 'no manual' use with screens that include bargraphs and trends in addition to copy/paste and delete functions for fast program building. With 100 programs, each with up to 300 steps and infinite program repetition, the possibilities are extensive for complex temperature control applications.
In addition, the GF_PROMER has a complement of programmable enable inputs and 16 programmable event outputs and may be used either as a standalone centralised controller or as a part of a distributed control system using fieldbus options that include Modbus RTU, Modbus TCP, Profibus DP slave or CANopen slave. Programs can be integrated in supervision networks using these fieldbus options. Programming and status information can also be transferred via the built-in RS485, Ethernet or USB ports.
Graphics functions include immediate display of programming and monitor pages that allow process control by checking trends of variables, setpoints, numerical values, event output states and clearance inputs on a single screen. Individual channel pages also display bargraph, numerical data and current control status. The GF_PROMER also provides complete alarm control with password levels and saving of historical data via USB.
