Input Terminals and LEDs

The 12 inputs allow the system to receive signals from external devices in the robot's
environment. Controller-PC has 8 digital inputs and 2 analog inputs. Eight green LEDs,
which correspond to the digital inputs, light up when the inputs are on.
Controller-PC digital inputs are all configured as SOURCE. For proper I/O operation, a
paired source/sink connection is required. When connecting a Controller-PC input to an
external device, be sure the external device output is SINK (NPN) type.
The state of the inputs are read by software commands.

Digital Inputs

Make sure the power box is switched off before you make any I/O connections.
Digital Inputs 1 through 8 are activated by external devices' outputs which are connected
to corresponding inputs on the power box, in either of the following ways:
• A microswitch is connected to a SCORPOWER input and to a SCORPOWER input
ground.
• External voltage is connected to a SCORPOWER input and external ground is
connected to a SCORPOWER input ground.
Voltage and input states are as follows:
• External voltage of 0-1.5V DC relative to SCORPOWER ground turns ON the input.
• External voltage of 2.5-24V DC relative to SCORPOWER ground turns OFF the
input.
Do not connect voltage exceeding +24VDC to the digital inputs
