(b) Digital output interface DO-1
This is a circuit in which the collector of the output transistor is the output terminal. When the output
transistor is turned on, the current will flow to the collector 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: 40 mA or less, maximum current: 50 mA or less, inrush
current: 100 mA or less) A maximum of 2.6 V voltage drop occurs in the MR-J3-D05.
If polarity of diode is
reversed, MR-J3-D05
will malfunction.

Note. If the voltage drop (maximum of 2.6 V) interferes with the relay operation, apply high
voltage (maximum of 26.4 V) from external source.
(2) Source I/O interfaces (CN9, CN10 connector)
(a) Digital input interface DI-1
This is an input circuit whose photocoupler anode side is the input terminal. Transmit signals from

(b) Digital output interface DO-1
This is a circuit in which the emitter of the output transistor is the output terminal. When the output
transistor is turned on, current will be applied from the output to a load. A maximum of 2.6 V voltage
drop occurs in the MR-J3-D05.
