Transistor Remote I/O Terminals Section 4-3
The following diagram shows the wiring of the DRT1-ID16-1 Remote Input
Terminal.
Note 1. Wire colors in parentheses are the previous JIS colors for photoelectric
and proximity sensors.
2. The V terminals (terminal numbers 13 and 22) are connected internally, as
are the G terminals (terminal numbers 2 and 11). When I/O power is sup-
plied to terminals 13 and 2, power can be supplied to sensors from termi-
nals 22 and 11.
When the power supply exceeds 1.2 A, the power supply should not be in-
put through the terminals; an external power supply must be used instead.
