200 I/O CAPACITY
I/O units are not included in the basic versions of IRB 2000.
In all, there are 6 available I/O slots (max. 5 with option 405 Winchester memory included):
• digital I/O, 16 in/16 out, max. 6 units (1 slot per unit)
• analogue I/O, 4 in/4 out, max. 1 unit (1 slot)
• AD combined I/O, digital 16 in/ 16 out and analogue 2 out, max. 1 unit
( 1 slot)
• RIO remote link for Allen Bradley PLC, max. 1 unit (2 slots)
With regard to analogue and combined I/O, only one of the units can be used in the system at
the same time.
20X Digital I/O
Digital I/O unit
Inputs: 16 opto-connected
Rated voltage: 24 V DC
Current at rated input voltage: 5.5 mA
Outputs: 16 opto-connected, short circuit protected
Rated voltage: 24 V DC
Load capacity per output: 200 mA
Load capacity per group of 8 outputs: 1A
The unit is electrically divided into 4 parts, with 8 inputs or outputs in each part.
Each part requires a separate voltage supply as follows in accordance with one of
the following alternatives:
• Internal supply from the control system, not galvanically insulated from
the electronics in the cabinet.
• External supply, galvanically insulated from the electronics in the cabinet.
Voltage range 19-35 V DC.
Connection points for the internal and the external supplies are provided in the system.
Reserved I/O groups.
Four groups of digital I/O may be reserved via the system parameters:
system I/O
remote control
weldequipment (AW)
drive units (AW)
gripper 3-8 (GL, MH/ASST)
digital gluing I/O
SWI (GL, MH/ASS'Y)
Contents and effects of reservations are described below.
