New miniature fieldbus modules for "in the machine" applications
MTE Turck introduces the new Turck bus-stop generation of miniature fieldbus connection modules specifically designed to fit inside a machine and provide a variety of connection options to all the major fieldbus protocols.
The rugged design allows remote I/O to be installed directly in a machine without the need for an enclosure. Units are watertight to IP67 with encapsulated electronics, making them ideal for wet or dirty industrial environments. They are extremely small and all the major fieldbus protocols are supported (see Plate 2).
The fieldbus connection is via a standard M12 socket or pin connector. Other connections are via snap-on M8 or screw type M12 units.

The main connection module connects to the specific protocol, such as Profibus, Interbus, DeviceNet, ControlNet, CAN open, InterBus, Lightbus, TCP/IP, RS232/485 or USB. Up to 254 extension modules that are independent of the fieldbus protocol can then be added via the IP-link fibre optic connection.
No configuration of the coupling modules is required and they offer a fast (1.5 Mbit/sec.) transmission speed, IP67 connectors, simple wiring in the field and a separate supply for the module and outputs for flexible emergency functions.
The compact extension modules, measuring only 126mm x 30mm x 27mm are available for a wide variety of signals, such as analogue, discrete, special and even, one with PLC functionality.
The new Turck bus-stop modules are a novel but logical step in the development of fieldbus technology. They will certainly speed the use of fieldbus by OEMs and users and are ideal for use with the comprehensive range of Turck and Banner sensors offered by MTE Turck.
