Wiring I/O Units
When connecting a Transistor or Triac Output Unit to an output device having a
high surge current (such as an incandescent lamp), care must be taken to avoid
damage to the Output Unit. The Transistor and Triac Output Units are capable of
withstanding a surge current of ten times the rated current. If the surge current
for a particular device exceeds this amount, use one of the following circuit con-
figurations to protect the Output Unit.
The above circuit protects the Output Unit by letting the load draw a small current
(about one third the rated current) while the output is OFF, significantly reducing
the surge current. The following circuit reduces the surge current by employing a
current-limiting resistor.
A Transistor Output Unit’s output cannot be directly connected to a TTL input
because of the transistor’s residual voltage. When connecting TTL circuits to
transistor Output Units, connect a pull-up resistor and a CMOS IC between the
two.
The following examples illustrate how to connect I/O devices to I/O Units. During
wiring, work slowly and carefully. If an input device is connected to an Output
Unit, damage may result. Check all I/O devices to make sure they meet the spec-
ifications. Be sure to allow for leakage currents and load inductance.
