Accura 2750D[C/CI] Motor-Unit Protection[Control] HMI Module
Installed at the front of individual motor-units, Accura 2750D[C/CI] is connected with Accura 2750P[C] with the Ethernet cable. When measuring the output power of the inverter in the inverter-unit, Accura 2750INV/VOL module is installed to measure the inverter output voltage. Using the Ethernet cable, Accura 2750DCI and Accura 2750INV/VOL are connected with Accura 2750INV/VOL and Accura 2750PC, respectively. Accura 2750D[C/CI] module collects information on the measurement, protection and operational status of Accura 2750P[C] and Accura 2750LC[I] of the motor-unit via internal communication and provides various information for users through the LCD screen. You can also configure all functions of Accura 2750P[C] and some functions of Accura 2750LC[I] on Accura 2750D[C/CI] module. In addition to Accura 2750D's features, Accura 2750DC provides the RUN and STOP buttons on the front for motor start/stop controls. Along with the functions of Accura 2750DC, Accura 2750DCI provides the INVERTER/BYPASS and AUTO/MANUAL buttons on the front for the operation of the inverter. Accura 2750D supports redundancy of Accura 2750P module by connecting two Accura 2750P modules simultaneously via its two built-in communication ports. Accura 2750DC[I] supports redundancy of Accura 2750PC module by connecting one Accura 2750PC module with one Accura 2750P module simultaneously via its two built-in communication ports.
