Source/Sink Output - Mitsubishi Electric MELSERVO MR-J5 Series User Manual

Source/sink output

For SDO3PA/SDO3NA and SDO3PB/SDO3NB, different output methods can also be used in combination in A-system and B-
system, such as SDO3NA as a source output and SDO3PB as a sink output. SDO3N_ is the source output type (when the
output transistor is turned on, the current flows from the output terminal to a load). SDO3P_ is the sink output type (when the
output transistor is turned on, the current flows from a load to the output terminal).
A lamp, relay, or photocoupler can be driven. Connect a diode to the path for an inductive load, or connect an inrush resistor
suppression resistor to the path for a lamp load. (Rated current 5 mA to 40 mA, maximum current 50 mA, inrush current 100
mA)
A voltage drop of 2.4 V occurs in the MR-J5-_G_-HS_.
