1, 4, 8 or 18 Channel DF1 PLC Analog Output Board
Description
The df1_xxao I/O board provides 1, 4, 8 or 16 analog output channels to a SCADAPack E Series
RTU to communicate with an Allen Bradley PLC peripheral I/O device via a serial connection. The
analog channels can be connected to an Integer or Real variable within an ISaGRAF application.
The connected I/O points are continuously controlled by the Current Value of the ISaGRAF
variable. This information is cache internally by the RTU and made available to the I/O point.
