Do1_ To Do3_ Source Output; Do4Na Source Output And Do4Nb Sink Output - Mitsubishi Electric MR-D30 Instruction Manual

3. SIGNALS AND WIRING

3.3.3 DO1_ to DO3_ source output

When the output transistor is turned on, the current will flow to the output terminal to a load. A lamp, relay, or
photocoupler can be driven. Install a diode (D) for an inductive load, or install an inrush current suppressing
resistor (R) for a lamp load. (Rated current: 5 mA to 40 mA, maximum current: 50 mA, inrush current: 100
mA or less) A maximum of 2.4 V voltage drop occurs in MR-D30.

3.3.4 DO4NA source output and DO4NB sink output

DO4NA as source output and DO4PB as sink output can be combined to use. As for DO4NA, when the
output transistor is turned on, the current will flow from the output terminal to a load. As for DO4PB, when the
output transistor is turned on, the current will flow from a load to the output terminal. A lamp, relay, or
photocoupler can be driven. Install a diode (D) for an inductive load, or install an inrush current suppressing
resistor (R) for a lamp load. (Rated current: 5 mA to 40 mA, maximum current: 50 mA, inrush current: 100
mA or less) A maximum of 2.4 V voltage drop occurs in MR-D30.
