Sink Input - Mitsubishi Electric MR-D30 Instruction Manual

3. SIGNALS AND WIRING
(3) Switch connection (when executing a test pulse diagnosis)
The pulses for diagnosis will be outputted from PLSA and PLSB. Wire so that the pulse signals
outputted from PLSA and PLSB pass through the switch.
(Test pulse diagnosis enabled)

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 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)
