ABB SPASI23 RTD analog input module
The I/O connections of the DCV 700are in the Application Controller
(APC) and in the Digital Drive
Controller (DDC).
The Application Controller APC includes:
• 4 digital inputs
• 2 digital outputs
• 2 analogue inputs
• 1 voltage reference output
The I/O connections in the Drive Controller DDC
are used for safety and other drive specific
functions like emergency stop and motor temperature measurement:
• 3 digital inputs
• 4 digital outputs
• 5 analogue inputs
• 2 analogue outputs
• 1 pulse encoder input
• 1 emergency stop input
• 1 emergency stop output
• 1 current source
• 1 voltage reference output
• 1 actual armature current output
Optional I/O boards are available
to provide tailored solutions for the
most demanding applications.
The quantity of I/Os can be increased by using
extended I/O board and speed measurement
board.
Extended / Remote I/O Board YPQ110A
Connection to the APC can either be through
parallel bus (extended) or through low speed
serial bus (remote).
• 8 digital inputs
• 8 digital outputs
• 4 analogue inputs
• 2 analogue outputs
• 3 voltage reference outputs
Speed Measurement Board YPH107A
The board can be used for accurate speed and
position measurement. Connection to the APC is
through the parallel bus. For positioning there is
a 32 bit hardware counter.
• 1 digital input for synchronisation
• 1 pulse encoder input
• 2 analogue outputs

Various communication boards are available to
provide communication links between the APC and
overriding control systems.
UART Board YPK113A
The UART board, YPK113A, is used to commu nicate with other overriding systems. Protocols
for Siemens Simatic S5 and Allen Bradley DH are
available together with SAMI protocol.
AF100
Advant Fieldbus 100 is a high-speed serial bus,
which is used for communication between APCs
or between an APC and an overriding system
such as ABB’s Advant Controller AC400-family.
The bus administrator board CI626 (BA) is needed
for controlling the bus when not using the Advant
Controller AC450. The communication board
YPK112A is used to connect the APC to the
Advant Fieldbus 100.
