Turck has introduced its TBPN safety block I/O module, which it claims is the first I/O block module to combine both standard and safety inputs/outputs in a single device.
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. Furthermore, the module offers two channels of internal safety outputs that can be used 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. Safety logic is created using the company’s safety configuration and diagnostics software tool; 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 two amps. Two of these ports can also be configured as IO-Link masters. In combination with the company’s I/O hubs, TTBIL-M1-16DXP, users can connect up to 32 additional discrete I/O points to the module.
