2.3 Outline of Digital Signal Output Circuit

There is a sink type (DX1*0) digital signal output circuit and source type (DX1*1) digital signal
output circuit. Use this circuit within the range shown below.
Output circuit
24VDC(+)
Output conditions
<Caution>
* When using a conductive load such as a relay, always connect a diode (withstand voltage 100V
or more, 100mA or more) parallel to that load.
* When using a capacity load such as a lamp, connect a protective resistance (R=150ohm)
serially to that load to limit the rush current. (Make sure that the current is lower than the
tolerable current including the momentary current.)
CAUTION
When using a conductive load such as relays, always contact a diode in parallel to the load as a
noise measure.
When using a capacity load such as a lamp, always connect a protective resistor serially to the
load to suppress rush currents.
