Connection Of I/O Interface; Source Output - Mitsubishi Electric MR-D30 Instruction Manual

3. SIGNALS AND WIRING

3.3 Connection of I/O interface

The following shows a connection of I/O interface. Refer to this section and make connection with an
external device.

3.3.1 Source output

This is an input circuit in which the anode of the photocoupler is the input terminal. Transmit signals from
source (open collector) type transistor output, relay switch, etc.
The wiring differs depending on a device to be connected, and on whether or not a test pulse diagnosis is
executed. Refer to section 4.4.1 for the test pulse diagnosis. (Rated current: 5 mA, maximum current: 10
mA)
(1) Connection of external device
Connect the output signal of external device to DI _ _.
(2) Switch connection (not when executing a test pulse diagnosis)
Wire without using PLSA and PLSB.
(Test pulse diagnosis disabled)
