4.3.1 All digital I/O common specifications
This section describes the electrical specifications for 24V digital I/O using an electrical cabinet. Can be
divided into: V + power selection, security I / O configuration.
The electrical cabinet supports 16 digital inputs and 16 digital outputs, as shown in Figure 4-2.
Figure 4-2
The digital I/O can be powered by a 24V power supply provided inside the control cabinet and supports
up to 1.5A output (overload will turn off the output). When the user needs more power output, the V+ power
supply can be powered by an external "24V power supply". 24V is the internal power supply and 0V is the
internal ground. V+ is the positive pole of the digital I/O interface, and V- is the negative pole of the digital I/O
interface. The factory default configuration is internal power, see Figure 4-3 below.

The electrical cabinet has a dedicated safety I/O interface, and the user can configure two functions:
emergency stop and protection stop. The function description is detailed in section 4.3.7. Here are some
examples of how safe I / O interface.
1. Factory configuration.
Users can use the robot without any additional safety equipment. If EI1~2 and SI1~2 are both connected
to V+, V+ is connected to 24V, and V- is connected to 0V, it indicates that 24V power is provided inside the
electrical cabinet. As shown in Figure 4-4.

2、Connect the emergency stop switch.
The user needs to use one or more additional emergency stop or guard stop switches, please refer to
Figure 4-5 and Figure 4-6 for wiring. Figure 4-5 and Figure 4-6 show how to use one or more emergency stop
switches.
The example uses an internal 24V power supply and the user can also use an external 24V power
suppl
y.

3. Connect the protective stop switch
Protective stop function, support automatic recovery. The electrical cabinet door switch is an application
case of the protection stop device, and the robot stops when the electrical cabinet door is opened. The wiring
diagram is shown in Figure 4-7.
