Application notes
This is the larger, safety-only sibling of the combined safe, standard and IO-Link module: eight safe channels in the L5 housing mean a whole machine zone of emergency stops, guard-door switches and safety mats can be collected on one PROFINET node. The datasheet states SIL 3, PL e, an IP65, IP67 and IP69K rated housing and a supply range of 20.4 to 28.8 VDC. Safety-relevant wiring and parameterisation must follow the manufacturer manual.
Installation hint: set the PROFIsafe address and safety parameters with the engineering tool, use the connectors and supply range from the table, and wire safety sensors as described in the manual. Cap unused ports to keep the IP rating.
Ordering code and what to confirm
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 100001826 identifies this exact module.
Points to confirm with us before ordering: the safety function and required SIL or performance level for each channel, the connector types, the supply range and the hazardous-area conditions in the manual, and the PROFIsafe parameters of your safety controller. 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.
