11.22.8 Digital Input Interface Card (OPC-DI)
The digital input interface card is equipped with a 16-point digital input terminal (SINK/SOURCE method switching
possible), and by installing the card in FRENIC-MEGA, the frequency can be set, and general-purpose input
terminals can be extended with a binary code (8, 12, 15, 16 bits) or BCD code (4 digits).
Applicable ports
This interface card can be installed in one of the three FRENIC-MEGA option connection ports (A, B, and C ports).

Function
[I1] to [I16]
Digital input 1 to 16
(1) The frequency can be set using the frequency setting
methods set with function codes o19 and o20.
Refer to “Function code settings” on the following page
for details.
(2) By setting function code o101 to o116, these terminal
signals can be used as general-purpose input signals in
the same way as terminal [X1] to [X9].
(3) The SINK/SOURCE method can be switched using SW1.
