Carbolite
temperature control systems

A choice of control systems is available including controllers which simply heat up the furnace and hold at one temperature indefinately and more complex programming systems. Access to parameters is simple and easy to understand and is customised to present only those parameters which need to be viewed or adjusted.

Carbolite 201 Controller

Carbolite 201 Controllers

The 201 is a three term PID microprocessor controller with the facility of an adjustable single ramp rate to setpoint, either up or down. It is a high precision instrument exclusive to Carbolite and is jointly designed by Eurotherm and Carbolite.
The measured temperature is provided by large LED's located behind a wipe clean membrane panel. The setpoint is displayed and adjusted by pressing either the 'raise' or 'lower' button.
Eurotherm 2416 CC

Eurotherm 2416 CC

The Eurotherm 2416 CC is an advanced setpoint programming temperature controller with eight segments, any of which can be a ramp, set or dwell. It is housed in a compact 1/16 din size measuring 48mm x 48mm high.
It provides precise control with the advanced PID control algorithm giving stable 'staight-line' control of the process. Power feedback is used to stabilise the output power and hence the controlled temperature against supply voltage fluctuations. The controller continually corrects for drift and this gives high stability and rapid response to process changes.
Eurotherm 2408 CP

Eurotherm 2408 CP

The Eurotherm 2408 CP contains the same features as the 2416 CC, but with 16 segments and is housed in a 1/8 din size measuring 48mm x 96mm high. The larger case allows for more options including storage of up to 20 separate programmes.

Overtemperature Protection

An independent overtemperature protection system may be justifiable to protect expensive heating elements or valuable furnace contents. Where the Carbolite 201 controller is the main controller, an overtemperature protection facility is integrated into the same display panel and incorporates an independent power supply and control circuit.
When required with other main controllers, a separate Eurotherm 2132 digital controller is fitted. This unit is housed in a 1/32 din size measuring 24mm x 48mm wide. The additional control unit uses a separate thermocouple and operates a contactor to shut down the furnace in the event of the set temperature being exceeded.

Eurotherm 301 PID Controller A PID controller with a large display mounted behind a smooth wipe-clean membrane. It has a single ramp to setpoint facility, and incorporates a process timer function. RS232 comms is available as an option at time of order. Made by Eurotherm exclusively for Carbolite.
Eurotherm 3216P5 PID Controller An 8 segment-pair programmer, in which each segment pair is a ramp followed by a dwell (the dwell can be of zero time).
RS232 or RS485 comms may be fitted as an option. This programmer is specially made by Eurotherm for Carbolite.
Eurotherm 3508P1 PID Controller These versions are like the 3508P1, but have 10 programs with a total of 50* available segments, and 25 programs with 100*, respectively. For example a single program of 50 segments could be created. The programs may be linked.

* the numbers of segments in the multi-program models is to be increased at some time in 2005.


Communications Software

IPSC communicates with one programmer at a time and allows data logging. It also shows a graph of furnace temperature and setpoint on the computer screen and allows storage of programs on disk, and easy editing and error free downloading to the furnace programmer.

Other Options

Additional control systems can be supplied and they include cascade control, multi-segment programmers and process timers. The Carbolite 201 controller is also available with an integral process timer. When the working setpoint is reached, a timed period starts and can either end with an audible alarm or be set to switch off the power at the end of the time period.

Standard Electrical Supply

When ordering, always quote the model, controller and the preferred type of electrical supply from the list. Please indicate the frequency (50 or 60 Hertz) and number of phases. For 3-phase supplies (where applicable), please state whether a neurtral is available (If so, please quote both the phase-to-phase and the phase-to-neutral voltages, eg 380.220V) Typical single phase voltages are 100, 110, 200, 208, 220, 240 and 254V. 3-phase voltages without neutral are typically 220, 380, 415 and 440V. 3-phase voltages with neutral are typically 220/127, 380/220, 415/240 and 440/254V.
