13.4 Detailed description 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 13.2. Refer to this section and make connection with the external device.
13.4.1 Sink I/O interface
(1) Digital input interface DI-1
This is an input circuit whose photocoupler cathode side is the input terminal. Transmit signals from sink
(open-collector) type transistor output, relay switch, etc.

(2) 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 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 5.2 V voltage drop occurs in the servo amplifier.

Note. 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.
