8.3.1 Common specifications of all digital I/Os
This section defines the electrical specifications of the following 24V digital I/Os of
the control box.
• Safety I/O.
• Configurable I/O.
• General purpose I/O.
It is important to install the Elite robot in accordance with the electrical specifications which
must be done for both two types of inputs. The internal 24V power supply shall be provided to
the digital I/O, and access of the power interface shall be implemented through the J14 terminal
on the IO plate via the internal 24V power supply.
The configurable I/O is defined that the digital input may be configured to two input modes
including NPN and PNP, which may implement selection with J22 on the IO plate. The NPN
input is default, namely, J22 short-circuit 24V and the intermediate terminal. Furthermore, the
short-circuit may be implemented for the GNDP and J22 intermediate terminal with a short
circuit cap, as to configure the input as the PNP mode.
The electrical specifications of the internal power supply is shown below.
Terminal Parameter Min Type Max Unit
Internal 24V power supply
[24V - GNDP] Voltage 22.8 24 26.4 V
[24V - GNDP] Current 0 -- 4 A
The digital I/O should be constructed in compliance with IEC 61131-2. The electrical
specifications are shown below.
