■Source I/O interfaces (CN9, CN10 connector)
• Digital input interface DI-1
This is an input circuit whose photocoupler anode side is input terminal. Transmit signals from source (open-collector) type
transistor output, relay switch, etc.

• Digital output interface DO-1
This is a circuit of emitter output terminal of the output transistor. 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.

Wiring CN9 and CN10 connectors
Handle with the tool with care when connecting wires.
■Wire strip
• Use wires with size of AWG 24 to 20 (0.22 mm
make the stripped length 7.0 mm  0.3 mm. Confirm the stripped length with gauge, etc. before using the wires.
• If the stripped wires are bent, loose, or too thick due to twisting too much, fix the wires by twisting lightly, etc. Then, confirm
the stripped length before using the wires. Do not use excessively deformed wires.
• Smooth out the wire surface and stripped insulator surface.
■Connecting wires
Before connecting wires, be sure to pull out the receptacle assembly from the header connector. If wires are connected with
inserted connector, the connector and the printed board may malfunction.
• Using extraction tool (1891348-1 or 2040798-1)
