Output conditions
Insulation method Non-insulation
Rated load voltage +24VDC
Max. output current 60mA/1 point (fixed value)
Output delay time 40µs
(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 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 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 ) serially to the load to suppress rush currents. (Make sure that the
current is less than the above tolerable current including the momentary current.)
