IP67 IO-Link Modules for EtherNet/IP
Note!
The shell of each Power IN/OUT connector is connected to PE screw tab.
Refer to Earth connection part
Note!
7/8” accessories (cordsets, plugs …) connected to the module power connectors shall
be screwed with a torque of 2.0 Nm to ensure a correct sealing to achieve IP67 rating.
Warning!
User has to verify that the maximum current consumption that can be reached ( e.g. all
output active at the same time,…) is lower than the maximum limit on all the range of
temperature supported by the application
Warning!
A overcurrent protection (ex: fuse) shall be added in front of IO modules to avoid
possible destruction in case of over-current situation
Power supplies
The HarshIO module can be powered by 2 separate power supplies:
• UB power supply is used to power:
o Module’s logic
o Digital inputs (I/O connector Pin 1)
o Standard Input/ Output SIO and IO-Link (I/O connector Pin 4)
• UL power supply is used to power:
o Digital outputs only (I/O connector Pin 2)
o It also provides extended power to Brad IO-Link digital hub (I/O connector Pin 2)
o
There is no separate grounding between UB and UL. It means that 0V (UB) and 0V (UL) are connected.
The +24 voltage can be applied on Module/Inputs power supply (UB) and Outputs power supply (UL) from
separate or unique power supply source.
Note!
You can only apply +24 voltage on UB if you only use the inputs.
The maximum amperage capability of the power connectors is limited to 8A and users have to make sure that
the current consumption of the HarshIO module, the connected devices to the IO ports as well as the
subsequent daisy chained modules would not exceed this consumption limit.
Note!
UB & UL support a power interruption according to EN 60204-1.
Note!
If you only use digital input devices, there is no need to supply power on UL.
UL is only required for Outputs on Pin2 or Extended power supply for Molex IO-Link
I/O Hubs.
