Notes on Parallel Input
• The AX40 accepts (+, -) common. To prevent input signal chattering, this device a non-contact input
(transistor etc.). If chattering occurs, inputs can be missed, and input recognition may be delayed.
• Be careful when using only full-wave rectification (including ripples) power supply for DC input, as it
may cause abnormal operation.
• If input power supply to the device is not turned off when using 2-line photoelectric sensor (or
proximity sensor) is used, connect bleeder resistance.
• When there exists an LED lead switch such as an LED switch at input contact, take care that the
voltage more than "ON" voltage is not applied to the input terminal of the AX40.
• When current is leaking from the input side, input may not be turned off. In such a case, connect
resistance using the diagram below.
• The START common is a specialized terminal. Do not use it together with other common lines.
