Use the PULS(65), SPED(––), ACC(––), PWM(––), and SYNC(––) instructions
to produce pulse outputs (rather than normal outputs) from output bits IR 01000
and IR 01001. Pulse outputs are possible from CPU Boards with transistor out-
puts only.

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.
Inductive Loads
When connecting an inductive load to an input, connect a surge protector or
diode in parallel with the load.
The surge protector’s components should have the following ratings:
