The 2416 is a versatile, high stability, fully configurable temperature or process controller, with self and adaptive tuning, in a 1/16 DIN size. It has a modular hardware construction that will accept up to three plug-in I/O modules and one communication module. The 2416 can also be set up with a simple 8 segment setpoint profile. More powerful versions are available that will run one 16 segment program or store 4 programs of 16 segments. An advanced PID control algorithm gives stable 'Straight-line' control of the process and 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.

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.

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.
