Output Part
100-mA output circuit by power MOSFET
Item Specification
Number of output points 10 points
Rated load voltage 24 VDC; 60 VDC (peak) (without flywheel diode)
Maximum load current 100 mA per point
Residual voltage 1.8 V / 100 mA
Isolation method Photocoupler
Overcurrent protection Fuse resistance: 10 , 0.1 W
Internal circuit configuration (Standard NPN specification)
 Supply 24 VDC between COMOA and COMOB. COMOA and COMOB have no polarities.
 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).
