Typical use and installation notes
Safety and standard signals share one housing and one network cable, so an emergency stop, a light curtain and a few ordinary sensors can all be wired at the machine. The datasheet lists safety rating SIL 3 according to IEC 61508 and performance level e according to EN ISO 13849-1, with two secure inputs and secure channels that can work as inputs or outputs, plus IO-Link ports for smart sensors. The safety function still has to be validated in the machine, using the manual and the safety documents.
Commissioning of any safety node needs a documented validation: check each safety channel, the reaction time and the diagnostics in the safety controller, and keep the manual and certificates in the machine file.
Selection check before ordering
TBPN is the Turck PROFINET and PROFIsafe block family; the datasheet title lists the safe digital channels (FDI inputs, FDX configurable channels), standard channels and IO-Link ports in this module. Ident number 6814053 identifies this exact module.
Points to confirm with us before ordering: the PROFIsafe parameters of your safety controller, the connector types, the safety function and required SIL or performance level for each channel, and the supply range and the hazardous-area conditions in the manual. Everything in the table comes from the datasheet as published, so the maker document is the final reference.

About brand
Turck is the German automation company for sensors, connectivity, fieldbus I/O and interface technology. It grew from Hans Turck's engineering office in Mülheim an der Ruhr: in 1965 a chemical plant ordered an isolation amplifier for intrinsically safe circuits, and the first 20 units were built by his brother Werner Turck in Halver. The family-owned Turck group is still headquartered in Mülheim an der Ruhr, with production in Halver and other sites.
Seven Star LLC is an independent supplier in Muscat. We list Turck sensors and I/O devices for machine builders and maintenance teams in Oman and the GCC.

Turck product series
Most of the Turck products here are inductive proximity sensors: threaded M12, M18 and M30 barrels in flush (BI) and non-flush (NI) versions, uprated-range (U) sensors, rectangular CP40 and CP80 housings and BIM magnetic-field sensors for detecting pistons in pneumatic cylinders. The type code describes the sensor; in BI5-M18-AP6X-H1141, BI means flush mounting, 5 is the switching distance in mm, AP6X a three-wire PNP output and H1141 the M12 connector.
Turck also makes RU ultrasonic sensors, PS pressure, TS temperature and LS level sensors, FCI inline flow sensors, the CMVT vibration and temperature sensor for condition monitoring over IO-Link, and fieldbus and Ethernet I/O modules and communication components.
Where Turck sensors are used
Position detection on conveyors, packaging machines, presses and robotic cells; level, pressure and temperature monitoring on hydraulic units and process skids; and vibration monitoring on motors, pumps and fans.
