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. The input covers all

standard thermocouples, the

Pt100 resistance thermometer

and linear millivolts, milliamps or

DC volts.

Input filtering from 1.0 to 999.9

seconds is included.

Customised operation

Custom LEDs provide 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.

The 2208 is a precision PID

temperature controller, with self-

tuning, in an 1/8 DIN size

(48x96x103mm). It has a modular

hardware build with the option of

two control outputs, two alarm

relays, and a communications

port. Two digital inputs are

included as standard. The control

outputs can be configured for

heating, cooling or alarms. The

2208 is fully configurable on-site.

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 PID values and to

calculate the overshoot inhibition

parameters. 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 on fan, water

and oil cooled systems.
