3 For Your Safety
The product is designed according to state-of-the-art technology. However, residual risks still exist.
Observe the following warnings and safety notices to prevent damage to persons and property.
Turck accepts no liability for damage caused by failure to observe these warning and safety notices.
3.1 Intended Use
These devices are designed solely for use in industrial areas.
The Turck IO-Link master modules BL20-E-4IOL(-10) or respectively BL67-4IOL are technology mod-
ules of the modular I/O-systems BL20 and BL67. They can be connected to several fieldbus systems
and Ethernet protocols via the respective gateways. They transmit signals of the connected IO-Link
devices to the gateway which, depending on the type of gateway, communicates with the higher
level controls via different fieldbus or Ethernet protocols.
3.2 General Safety Instructions
The device may only be assembled, installed, operated and maintained by professionally trained
personnel.
The device may only be used in accordance with applicable national and international regula-
tions, standards and la
ws.
The device only meets the EMC requirements for industrial areas and is not suitable for use in res-
idential areas.

4 Product description
The Turck IO-Link master modules BL20-E-4IOL(-10) or respectively BL67-4IOL are technology mod-
ules of the modular I/O-systems BL20 and BL67. They can be connected to several fieldbus systems
and Ethernet protocols via the respective gateways.
The IO-Link module provides 4 IO-Link master channels and 4 universal digital channels (PNP).
The four IO-Link channels can be parameterized independently and can optionally be operated in
IO-Link mode (IOL) or in standard I/O mode (DI mode).
The four universal digital channels are designed as XSG-channels and can therefore be parameter-
ized as in- or output.

ATTENTION!
Insufficient fuse protection of UL
Damage to the electronics
ULhas to be protected by a fuse with max. 8 A/10A (depending on type of gateway).
More information can be found in the respective gateway manuals.
ATTENTION!
