Internal circuit configuration (Standard NPN specification)

 Supply 24 VDC between COMOA and COMOB.

 Pin Nos. 1 & 2, and 3 & 4, are connected internally.
Note 1) The output circuit is an open-drain circuit provided by a power MOSFET and has no flywheel diode.

When connecting a load, such as a relay, also connect a diode, etc., to suppress flyback voltage.
(Spike noise can be eliminated most effectively when a diode is connected at the closet possible
position to the coil).
