(2) Detailed explanation of interfaces
This section provides the details of the I/O signal interfaces (refer to the I/O division in the table) given in
section 11.5.3. Refer to the following and make connection with the external device.
(a) Digital input interface DI-1
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 following is a connection diagram for
sink input.

(b) 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 will flow from 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 in the servo amplifier.
The following shows a connection diagram for sink output.

If polarity of diode is
reversed, servo amplifier
will malfunction.

Note. If the voltage drop (maximum of 2.6 V) interferes with the relay operation, apply a
high voltage (maximum of 26.4 V) from an external source.
