Temperature Controllers

Complete operator interface, protected by Lexan membrane to guarantee an IP65 faceplate protection level.
Composed of 4 keys, double 4-digit green LED display, 4 red signal LEDs for the 4 relay/logic outputs and 3 additional LEDs with programmable function to signal the instrument’s various function states.
The main input for the variable to be controlled is universal, and allows connection of a wide variety of signals: thermocouples, resistance thermometers, thermistors, normalized linear inputs, all with possibility of custom linearization set from the faceplate. Input type is selected entirely from the faceplate and requires no external adapter shunts/dividers.
A second auxiliary analog input from current transformer is available. You can select one of the two presettable setpoints, select Manual-Automatic mode, reset the alarm memory, or enable the hold function by means of the digital input.
The instrument provides up to 4 outputs: relay (5A, 250VAC/30VDC cosφ = 1) or logic (24V ± 10% (10Vmin a 20mA)).
An analog output in voltage or in current is also available. The functions of each output are freely configurable from the faceplate. In addition to the control and alarm outputs, you can also have outputs that repeat the state of the digital or retransmission input by process variable, setpoint, deviation, alarm trip points and values acquired via serial line.
An additional output (24VDC, 30mA max.) is available to power outside transmitters.
The serial communication option is RS485, with MODBUS RTU protocol and maximum speed of 19200 baud (485). The instrument’s entire programming procedure is made easier by grouping the parameters in function blocks (CFG for control parameters, Inp for inputs, Out for outputs, etc.).
The instrument can also select the parameters to be displayed based on its hardware configuration, which automatically hides irrelevant parameters.
The instrument is supplied with an “EASY” configuration calling for just a few parameters (only those pertaining to the model ordered and essential to the controller’s operation). In this way, you just have to set the setpoint and the alarm, then launch self-tuning with the specific button.
For even simpler configuration, you can use a PC programming kit consisting of a cable and a guided program for Windows environment.

Microprocessor controller, format 48×48 / 96×96 (1/8 DIN – 1/4 DIN) manufactured using SM Technology.

The instrument provides a complete operator interface, protected by a Lexan membrane that ensures level IP65 faceplate protection.

It has 4 keys, two green LED displays, each with 4 digits, 4 red indicating LED’s for the 4 logic or relay outputs, and a further 3 LED’s that are programmable to indicate the various operational states of the instrument.

The main input for the process variable is universal and provides the possibility to connect many types of input sensor: thermocouple type J, K, R, S, T, B, E, N, Ni-Ni18Mo, L; resistance thermometer Pt100 3-wires; thermistor PTC; ilinear inputs 0-50mV, 10-50mV, 2-10V, 0-10V, 0-20mA, 4-20mA, and potentiometer, all with the possibility of custom linearisation that can be defined using the faceplate keys.

The type of input is selected from the faceplate keys and no external shunts or adapter are required. A second auxiliary isolated analogue input is available, which can also be configured for a linear input (0-10V, 2-10V, 0-20mA / 4-20mA), for remote setpoint, potentiometer or current transformer.

The auxiliary input function is completely configurable, including the possibility of a custom linearization. It is possible to configure the 2 available isolated digital inputs for selection of up to 4 local setpoints; start, stop and reset of internal timer; Auto/Man, Loc/Rem functions; alarms memory reset; input hold function.

The instrument can have up to 4 relay (3A/250V) or logic (12Vdc, 20mA) outputs and up to 2 islolated analogue outputs in voltage or current.

The function of each output is completely configurable by faceplate.

The available functions include: control output, alarm output, timer, digital input repetition, retransmission of process value, setpoints, deviation, alarm setpoint or value read from digital communication.

The Heat/Cool adjustment offers the possibility of setting the cooling parameters in relation to the type of water, oil or air fluid.

A further isolated output (10 or 24Vdc, 30mA max.) is available for powering external transmitters or potentiometers.

The serial communication interface RS485 (RS232C compatible) makes it possible to read or modify any parameter and to govern the instrument online (local/remote manual/automatic commu-tation, internal timer control, direct control of outputs).

Protocols available: MODBUS RTU and CENCAL (Gefran).

Using these it is possible to write to any of the instrument parameters.

All the programming procedures of the instrument are facilitated by the grouping of the parameters in function blocks (CFG for the control parameters, Inp for the inputs, Out for the outputs, etc) and by the possibility of selecting a simplified menu for entering the most frequently used parameters.

To simplify the configuration even further, a programming kit is available for PC, which includes a menu driven configuration program for Windows and the necessary cable to connect the instrument.

Microprocessor controller, format 48×48 (1/16 DIN) manufactured using SMT.

Provides a complete operator interface protected by a Lexan membrane that ensures level IP65 faceplate protection.

It has 4 keys, two green LED displays, each with 4 digits, 4 red signal LED’s for the 4 logic or relay outputs, and 3 other programmable LED’s to signal the various operational states of the instrument.

The main input for process variable is universal, and many types of signals can be connected: thermocouples, resistance thermometers, thermistors, normalized linear inputs, all with possibility of custom linearization using the faceplate keys.

The type of input is selected from the faceplate keys; no external shunts are required.

A second auxiliary analog input from the current transformer is also available.

With the isolated digital input you can select: one of the two presettable setpoints, select Manual-Automatic mode, reset the alarms memory, or enable the hold function.

The instrument can have up to 4 outputs: relay (3A, 250V) or logic (12Vdc, 20mA).

An analog output in voltage or current is also available.

The function of each output is freely configurable from the faceplate keys.

In addition to control and alarm outputs, you can have outputs that repeat the state of the digital or retransmission input by process variable, setpoint, drift, alarm limits and values acquired from serial line.

Another isolated output (at 10 or 24Vdc, 30mA max.) is available to power external transmitters.

The serial communication option (available in RS485 standard) allows connection to supervision systems and PLCs with two protocols: GEFRAN CENCAL and MODBUS RTU.

Instrument programming is facilitated by grouping parameters in functional blocks (CFG for control parameters, Inp for inputs, Out for outputs, etc.).

The instrument can also select display parameters based on hardware configuration, automatically masking irrelevant parameters.

The instrument is supplied with an “EASY” configuration with just a few parameters (only those for the model ordered and essential for controller operation).

In this way, you just have to set the setpoint and alarm, and launch selftuning from the button. The 600 does all the rest.
