3. SIGNALS AND WIRING
(3) Switch connection (executing a test pulse diagnosis)
The pulses for diagnosis will output from PLSA and PLSB. Wire so that the pulse signals outputted from
PLSA and PLSB pass through the switch.
3.3.2 Sink input
This is an input circuit whose photocoupler cathode side is input terminal. Transmit signals from sink (open
collector) type transistor output, relay switch, etc.
The wirings differ by device for connecting and executing test pulse diagnosis and not executing test pulse
diagnosis. 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 _ _.
