Interface
For the MR-J3-D05, source type I/O interfaces can be used.
■Sink I/O interface (CN9, CN10 connectors)
• Digital input interface DI-1
This is an input circuit in which the photocoupler cathode side is the input terminal. Transmit signals from a sink (open-
collector) type transistor output, relay switch, etc.
• Digital output interface DO-1
This is a circuit in which the collector of the output transistor is the output terminal. When the output transistor is turned on, the
current flows to the collector terminal.
A lamp, relay, or photocoupler can be driven. Install a diode (D) for an inductive load, or install an inrush current suppressing
resistor (R) for a lamp load. (Rated current: 40 mA or less, maximum current: 50 mA or less, inrush current: 100 mA or less) A
maximum of 2.6 V voltage drop occurs internally.
*1 If the voltage drop (maximum of 2.6 V) interferes with the relay operation, apply high voltage (maximum of 26.4 V) from external source.
