Output Terminals and LEDs

The 10 output terminals allow Controller-PC to transmit signals to external devices in the
robot's environment. Controller-PC has 4 digital relay outputs, 4 digital open collector
outputs and 2 analog outputs. Eight yellow LEDs, which correspond to the digital
outputs, light up when these outputs are on.
Controller-PC's digital outputs are all configured as SINK. For proper I/O operation, a
paired source/sink connection is required. When connecting a Controller-PC output to an
external device, be sure the external device input is SOURCE (PNP) type.

Digital Outputs

Make sure the power box is switched off before you make any I/O connections.
The digital outputs are activated by software commands.

Relay Outputs

Digital Outputs 1 to 4 include a relay in the final stage. Each relay includes the three
contact points:
• Common (C)
• Normally Closed (NC)
• Normally Open (NO).
In steady state (before the relay functions),
the NO terminal is disconnected from the
common line and the NC terminal is
shorted to the COM terminal.
When the relay functions, the situation
reverses; the NO terminal is shorted to the
COM terminal, and the NC terminal is
disconnected from the COM terminal.
Figure 4 shows the on and off states of the
digital relay outputs.
Maximum voltage allowed: 30V
Maximum current allowed: 1.5A
