Product Description
2416 Temperature Controller / Programmer
The 2416 is a versatile, high stability, temperature or process controller, with self and adaptive tuning, in a 1/16 DIN size (48x48x150mm). It has a modular hardware construction which will accept up to three plug-in I/O modules and one communication module. The 2416 is fully configurable on-site.
- High stability control
- Up to four 16 segment programs
- Heating and cooling
- Motorised Valve control
- Customised operation
The 2416 is also available in versions with a simple 8 segment setpoint profile or more powerful versions that will run one 16 segment program or store 4 programs of 16 segments.
Precise control
An advanced PID control algorithm gives stable ‘Straight-line’ control of the process. A one-shot tuner is provided to set up the initial PID values and to calculate the overshoot inhibition parameters. In addition an adaptive tuner will handle processes with continually changing characteristics. On electrically heated loads, power feedback is used to stabilise the output power and hence the controlled temperature against supply voltage fluctuations. Dedicated cooling algorithms ensure optimum control of fan, water and oil cooled systems.
Universal input
A universal input circuit with an advanced analogue to digital convertor samples the input at 9Hz and continuously corrects it for drift. This gives high stability and rapid response to process changes. High noise immunity is achieved by rejection of 50/60Hz pick-up and other sources of noise. Sensor diagnostics are also provided. The input will accept standard thermocouples, the Pt100 resistance thermometer and linear millivolts, milliamps or DC volts.
Input filtering from OFF to 999.9 seconds is included.
Customised operation
A custom LED display provides a bright, clear display of the process value and setpoint. Tactile push buttons ensure positive operation. Access to other parameters is simple and easy to understand and can be customised to present only those parameters that need to be viewed or adjusted. All other parameters are locked away under password protection. A front panel auto/manual button is provided.
Alarms
Up to four process alarms can be combined onto a single output. They can be full scale high or low, deviation from setpoint, rate of change or load failure alarms. Alarm messages are flashed on the main display. Alarms can be configured as latching or non-latching and also as ‘blocking’ type alarms, this means that they will become active only after they have first entered a safe state.
Digital communications
Available with either EIA485 2 wire or 4 wire or EIA232. With industry-standard protocols including: Modbus®, Eurotherm Bisync, and SPI.
