7.5 Outline of Digital Signal Output Circuit

The digital signal output circuit uses a sink type (DX1*0) or source type (DX1*1). Use within the
specification ranges shown below.
Output circuit
Output conditions
Insulation method
Rated load voltage
Max. output current
Output delay time
(Note) An output voltage of more than 60mA per point cannot be flowed.
* When using an inductive load such as a relay, always connect a diode (voltage
resistance 100V or more, 100mA or more) in parallel to the load.
* When using a capacity load such as a ramp, always connect a protective resistor
(R=150 Ω) serially to the load to suppress rush currents. (Make sure that the
current is less than the above tolerable current including the momentary current.)
CAUTION
When using an inductive load such as a relay, always connect a diode in parallel to the
load.
When using a capacity load such as a ramp, always connect a protective resistor serially
to the load to suppress rush currents.
