Turck TBEN-S2-8DIP Block I/O Module 8 PNP Inputs M8 PROFINET

Why choose the TBEN-S2-8DIP

TBEN-S2-8DIP is a compact multiprotocol I/O block with eight PNP digital inputs, a miniature 32 x 144 x 32 mm housing and M8 connections for the Ethernet bus and the supply.

Turck lists these features for it in the datasheet: Supports 10 Mbps/100 Mbps; Programmable ARGEE; Integrated Ethernet switch; Glass fiber reinforced housing; Diagnostics of the supply per I/O port; Protection classes IP65, IP67, IP69K; ATEX zone 2/22; Pin1 switchable per I/O port; Shock and vibration tested.

Technical specifications

Using it in the field

The same device runs as PROFINET, EtherNet/IP or Modbus TCP, with the protocol detected automatically, which allows one stock item for different PLC brands. Fully potted electronics, a glass-fibre-reinforced housing and IP65, IP67 and IP69K protection let it be mounted directly on the machine without a cabinet. Pin 1 is switchable per I/O port and the supply is diagnosed per port, details that help on machines with many sensors. The integrated Ethernet switch passes the bus on to the next device.

Installation hint: mount the block on a flat surface with the two fixing holes, use the supply and bus connectors the table lists, assign the IP address or use DHCP before connecting to the controller, and fit protective caps on unused ports so the IP65, IP67 or IP69K rating is kept. Check the power budget of the sensor and actuator groups.

Type code, ident number and checks

Derived from the datasheet titles: TBEN is the Turck block Ethernet family, S1 and S2 are the compact 32 mm wide housings with M8 connections, L4 and L5 are the larger housings with M12 connections (L4 with a 4-pin and L5 with a 5-pin 7/8-inch supply connector in the feature list), DIP means digital PNP inputs, DOP digital PNP outputs and IOL IO-Link master channels. Ident number 6814073 identifies this exact module.

A short checklist before you order: the supply connector, the fieldbus protocol and firmware needed by your PLC, the number and type of channels, the connector style (M8 or M12) of your sensors and valves, and any hazardous-area conditions in the Quick Start Guide. Specifications here are restated from the official datasheet and should be matched against the current maker revision.

Where a compact input block fits in a machine design

Machine builders use compact blocks such as the TBEN-S2-8DIP to collect digital signals close to where they originate instead of running individual sensor cables back to a central cabinet. Proximity switches, photoelectric sensors, limit switches and cylinder position sensors on conveyors, packaging lines, assembly stations and material handling equipment are typical signal sources for an eight-channel PNP input block. Placing the block on the machine shortens cabling, simplifies wiring diagrams and makes it easier to add or move a station later, because only the Ethernet and supply lines run back to the controller. The small housing suits tight spaces on moving modules and tooling, where a larger block with heavier connectors would be awkward to mount.

Integration with PROFINET, EtherNet/IP and Modbus TCP controllers

Because the protocol is detected automatically, the same block can be integrated into a PROFINET project, an EtherNet/IP network or a Modbus TCP system without ordering a different type. In an EtherNet/IP system the assembly instances and the Device Level Ring support listed in the table are the details the controller engineer will use; in a Modbus TCP system the register start addresses and supported function codes define how the PLC reads the inputs. The integrated Ethernet switch allows several blocks to be connected in a line, which keeps network cabling simple across a long machine. ARGEE programmability allows simple logic to run in the block itself where the application calls for it, although most installations treat the block purely as remote inputs for the main controller.

Planning the network addressing before commissioning saves time on site. Deciding whether each block uses a static IP address or DHCP, recording the address against the machine position and documenting which sensor is wired to which input make fault finding and later modifications far easier for maintenance teams.

Installation conditions in Oman and the GCC

Plants in Oman and across the GCC often combine high ambient temperatures, airborne dust and, in food and beverage or packaging facilities, regular washdown. The glass-fibre-reinforced housing, fully potted electronics and the listed protection classes are the features that let the block be mounted directly on equipment in these conditions rather than inside an enclosure. Mounting it out of direct sunlight where possible, routing cables so water runs away from connectors and keeping the M8 connections fully tightened all help preserve the rated protection. On sites with hazardous areas, the ATEX zone 2/22 listing should be checked against the area classification and the Quick Start Guide before the block is specified for that location.
