9.1.8.1 Drive I/O Port Outputs
The Drive I/O Port provides 4 source-only 24 Vdc outputs. For sourcing outputs, one
side of the load is connected to the Output pin on the Drive I/O connector, and the
other side of the load is connected to 24 Vdc Common.
These outputs get their power from Pin 3 of the I/O Power connector. Each of the 4
outputs on the Drive I/O connector is a solid state switch rated at 50 ma, and is short-
circuit and over-current protected. In addition, each output is protected with internal
clamping diodes. Without clamping, high voltage transients (kickback) from inductive
loads might damage the module. For safety reasons, all outputs turn off (no current
flow) when a the user program (Ladder) is not running (Scan Loss), or
communications to the Drive is lost.
9.1.8.2 Drive I/O Port Inputs
The Drive I/O Port also provides 4 sink/source 24 Vdc inputs.
To configure an Input as Sinking, the Sink/Source select pin (pin 6 for Inputs 5 and 6,
pin 5 for inputs 7 and 8), must be connected to 24 Vdc. When configured as Sinking,
one side of the input device is connected to the Input pin on the Drive I/O Port
connector, and the other side of the input device must be connected to 24 Vdc
Common.
To configure an Input as Sourcing, the Sink/Source select pin (pin 6 for Inputs 5 and 6,
pin 5 for inputs 7 and 8), must be connected to 24 Vdc Common. When configured as
Sourcing, one side of the input device is connected to the Input pin on the Drive I/O
Port connector, and the other side of the input device must be connected to 24 Vdc.
9.1.8.3 Drive I/O Port Wiring Example
An example of wiring the Drive I/O is shown in See Figure 9-5 on page 301 .
• Since the Outputs are sourcing, one side of the output device is connected to the
Output pin on the Drive I/O Port connector, and the other side is connected to 24
Vdc Common.
• The Sink/Source select pin for Inputs 5 and 6 on the I/O Power Port connector is
connected to 24 Vdc, making Drive Inputs 5 and 6 Sinking. In this configuration,
one side of the input device is connected to the Input pin on the Drive I/O Port
connector, and the other side of the input device is connected to 24 Vdc Common.
• The Sink/Source select pin for inputs 7 and 8 on the I/O Power Port connector is
connected to 24 Vdc Common, making Drive Inputs 7 and 8 Sourcing. In this con-
figuration, one side of the input device is connected to the Input pin on the Drive I/
O Port connector, and the other side of the input device is connected to 24 Vdc.
