Adept Cobra PLC600/PLC800 Robot User’s Guide, Rev C 71
NOTE: The input current specifications are provided for reference; voltage
sources are typically used to drive the inputs.
In the following figure, example 1 shows inputs (1001 to 1004) with a negative common,
example 2 shows inputs (1005 to 1008) with a positive common, and example 3 shows
inputs (1009 to 1012) with an independent power supply (no common).
NOTE: These are examples. Either method can be used on any channel.
Figure 4-13. Digital Input Wiring Examples (XDIO Connector)
NOTE: Power from pins 41-44 and 47-50 can be substituted for the
customer power supply. See Figure 4-14 on page 73 and Table 4-14 on
page 72 for additional information.
Output Signals
The XDIO connector handles output signals 0001 to 0008. Refer to Table 4-14 for output
specifications. The locations of the signals on the connector are shown in Table 4-15 on
page 74. The XDIO connector provides separate positive and negative connections for
each channel (no internal common connections). This allows the choice of wiring for
current-sourcing or current-sinking modes.
