TBPN hybrid safety block I/O modules saving space and cost

The TBPN safety block I/O module from Turck Australia is the first block
I/O module to combine both standard and safety inputs/outputs in a single

Designed to be adapted to the specific signal requirements of the
machine, Turck’s IP67 hybrid modules help users save valuable space and greatly
reduce overall system costs of their machines.

On the safety side of the PROFINET/PROFIsafe module, the user has two
safety inputs for connecting different safety sensors, such as light curtains
or emergency stop buttons. Two additional safety channels can be used either as
safety inputs or outputs. Two channels of internal safety outputs are also
provided to remove power to the universal discrete I/O ports as well as to one
of the IO-Link ports on the standard side of the block.

Turck’s safety configuration and diagnostics software tool is used to
create the safety logic; once programmed, device replacement is simplified by
means of a removable memory chip housed under the protective window.

For the standard side of the PROFINET/PROFIsafe module, four universal
discrete I/O ports are available for connecting general purpose signals and can
switch up to 2 amps. Two of these ports can also be configured as IO-Link
masters. In combination with Turck’s I/O hubs, TBIL-M1-16DXP, users can connect
up to 32 additional discrete I/O points to the module.

According to Dan Klein, product manager for Turck’s Fieldbus Technology
division, integrating or embedding safety functions into existing fieldbus
systems is a growing trend in automation. With Turck’s new hybrid safety IO
modules, users can gain this combined functionality in one block, simplifying
installation and maximising flexibility, without compromising the level of
safety and reliability expected.

Both the standard channels as well as an IO-Link channel of the TBPN can
be disconnected for safety-related applications, considerably simplifying the
wiring of auxiliary drives and valve blocks.

The robust safety module offers
an extended operating temperature range of -40¡C to +70¡C, while the IP65/IP67/IP69K
protection ratings allow use in the most demanding environments.
