11.22 Digital I/O interface card (OPC-DIO)
11-68
11.22 Digital I/O interface card (OPC-DIO)
This interface card can provide following features to the FRENIC-Ace series.
(1) Available to set frequency point with binary (8,12bit) or BCD code.
(2) Available to monitor with binary (8bit) code.
(3) Available to extend the digital input terminals as I1 to I13.
(4) Available to extend the transistor output terminals as O1 to O8.
Note: Two or more communication cards cannot be mounted simultaneously. And this card requires a mounting
adapter; refer to Section 11.19 .
Applicable ROM version
This card is applicable to inverters with a ROM version 0300 or later.
