The following diagrams show example applications of sink-type transistor out-
puts using output bits IR 01000 and IR 01001. Use the PULS(65), SPED(––),
ACC(––), PWM(––), and SYNC(––) instructions to produce pulse outputs (rath-
er than normal outputs) from output bits IR 01000 and IR 01001.

Output Wiring Precautions Observe the following precautions to protect the PC’s internal components.
Output Short Protection
The output or internal circuitry might be damaged when the load connected to an
output is short-circuited, so it is recommended to install a protective fuse in each
output circuit.
