Eight PID blocks, provide an extensive range of control strategies. Each block offers one-shot auto tuning to optimize control performance without the need for specialist knowledge. Every PID block may be a Single PID, Cascade, Ratio or Override controller, each providing the choice of analog, time proportioned, or valve position output.
Six base sizes are available to take from 2 to 16 I/O modules each. Up to 16 bases may be daisy chained to provide acquisition and multi-loop control solutions with up to 128 I/O per base.
DIN rail mounting allows the 2500 to be located where the control action is required, minimizing the cost of the cable used, as only the communications need be taken to the User Interface. The 2500 may also be mounted on part of the machine, saving the cost of centralized control cubicles.
A friendly Windows configurator package, ‘iTools,’ is used to set up the 2500. iTools parameterizes and commissions the I/O points, the Toolkit, and PID function blocks and interconnects the different variables, alarms, function blocks, and I/O. ‘Toolkit blocks’ provide local combinational logic and mathematical calculation.
