General Description
GEFRAN series 1200 / 1300 digital controllers
have been designed for temperature control in
any
applications involving heating or cooling
processes. They represent an exclusive combination
of
performance, reliability and applicational
flexibility. In particular, this new line of Gefran tempera-
ture
controllers is the ideal solution for application
in sectors where performance and service continuity are
important, including:
• extrusion lines
• injection molding for plastic materials
• thermoformers
• presses for rubber
• wrapping and packaging machines
• processing plant for the food industry
• cooling switchboards
• climatic chambers and test benches
• ovens
• paint plants
• etc.

1 • PRELIMINARY INSTRUCTIONS
The 1200/1300 series temperature controllers are
made on an extremely versatile hardware and software
platform, that allows the most suitable I/O composition
for the plant to be chosen from a series of options, up to
a maximum of:
• 4 outputs
• 3 inputs (2 of which are auxiliary)
• 1 RS485 interface.
Basic Version Controller
• 1 universal input for TC, 2/3 wire RTD, PTC, NTC,
• 2 standard outputs: one relay and the other
• functions heat/cool, self tuning, autotuning, soft start
• alarm for interrupted load or short-circuited probe
• service serial line for configuration by PC (Winstrum)
Options
• 3rd output retransmission relay/
• 4th output relay/logic
• 2 auxiliary digital inputs with configurable function,
• serial optoisolated RS485 interface
