6.5 Outline of Digital Signal Output Circuit
The digital signal output circuit uses a sink type (DX4
0, 3 0, 2 0) or source type (DX4 1, 3 1,
2
1). Use within the specification ranges shown below.

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.
∗ When using an inductive load such as a relay, always connect a diode (voltage
resistance 100 V or more, 100 mA or more) in parallel to the load.
∗ When using a capacity load such as a lamp, always connect a protective resistor
(R=150Ω) serially to the load to suppress rush currents. (Make sure that the
current is less than the above tolerable current including the momentary current.)
