ABB enhances Micro-DCI process control station
Warminster, Pa. – Version ‘B’ of 53MC5000 Series controller is the core of recently released Micro-DCI Series process control station products. The networkable controller, incorporates a hot-swappable operator interface display, ABB’s Easy-Tune self-tuning algorithm, and up to four loops of control. Standard, preconfigured control strategies include PID (with P, PI, PD, and I controller versions; Analog backup (controller acts as a signal selector with another controller); Ratio PID; Automatic/manual station; Two-loop control (two identical PID controllers); Two-loop cascade arrangement of two PID loops; Two-loop override; Four loop control; and Dual two-loop cascade (four PID loops in two traditional primary/secondary loop arrangement). Advanced control, such as dead-time compesation and more numeric/logic operations can be applied to the data using F-TRAN programming language. Micro-DCI Series 53MC5000B comes standard with four analog, two discrete inputs; two analog, two discrete outputs; RS-422/485 data highway; and RS-232 connections. Several module options allow expansion to nine analog/two discrete inputs; four analog/two discrete outputs; and 16 user-defined discrete I/O points.
