CFW-09 OPTIONS AND ACCESSORIES

This chapter describes the optional devices that are available for the CFW-09
and the accessories that may be necessary in specific applications. Options
include the Expanded I/O Boards (EBA/EBB), LED-only Keypad, Remote
Keypad and Cables, Blank Cover, RS-232 PC Communication kit, The
accessories comprise: Encoder, Line Reactor, DC Bus Choke, Load Reactor
and RFI filter, boards for Fieldbus communication, kit for extractable assembling,
NEMA 4X/IP56 line, HD and RB and PLC board line.
The I/O expansion boards expand the function of the CC9 control board. There
are four different I/O expansion boards available and their selection depends
on the application and extended functions that are required. The four boards
cannot be used simultaneously. The difference between EBA and EBB option
boards is in the analog inputs/outputs. The EBC1 board is used for the encoder
connection. The EBE board is for RS-485 and motor PTC. A detailed description
of each board is provided below.
The EBA board can be supplied in different configurations, combining some
specific features. The available configurations are show on table 8.1.
Included Features

NOTE!
The use of the RS-485 serial interface does not allow the use of the standard
RS-232 input - they can not be used simultaneously.
