Controller I/O

Description

You can use the I/O inside the Control Box for a wide range of equipment including pneumatic relays, PLCs and emergency stop buttons.

The illustration below shows the layout of electrical interface groups inside the Control Box.

 

 

You can use the horizontal Digital Inputs block (DI8-DI11), illustrated below, for quadrature encoding Conveyor Tracking. 

 

 

The meaning of the color schemes listed below must be observed and maintained.

Yellow with red text Dedicated safety signals
Yellow with black text Configurable for safety
Gray with black text General purpose digital I/O
Green with black text General purpose analog I/O

 

In the GUI, you can set up configurable I/O as either safety-related I/O or general purpose I/O.

 

Common specifications for all digital I/O

This section defines electrical specifications for the following 24V digital I/O of the Control Box.

  • Safety I/O.

  • Configurable I/O.

  • General purpose I/O.

The word configurable is used for I/O configured as either safety-related I/O or normal I/O. These are the yellow terminals with black text.

Install the robot according to the electrical specifications which are the same for all three inputs.

It is possible to power the digital I/O from an internal 24V power supply or from an external power source by configuring the terminal block called Power. This block consists of four terminals. The upper two (PWR and GND) are 24V and ground from the internal 24V supply. The lower two terminals (24V and 0V) in the block are the 24V input to supply the I/O. The default configuration uses the internal power supply.

 

Power supply default

In this example the default configuration uses the internal power supply

 

 

External power supply 

If more current is needed, you can connect an external power supply as shown below.

The fuse is Mini Blade type with maximum current rating of 10 A and a minimum voltage rating of 32 V. The fuse must be UL marked. If the fuse is overloaded, it must be replaced.

 

 

In this example the configuration uses an external power supply for more current.
