Beckhoff bus terminals
The robust housing, secure contacts and the solidly built electronics are prominent features of our components. A station consists of one Bus Coupler and up to 64 electronic terminal blocks. With the K-bus extension it is possible to operate up to 255 Bus Terminals on one Bus Coupler.
The electronic terminal blocks are clipped onto the Bus Coupler. They connect by simply latching together. This means that each electronic terminal block can be exchanged separately and can be mounted on a standard mounting rail. In addition to horizontal type mounting, all other mounting types are permitted in the majority of the cases. Show more
The Beckhoff Bus Terminal with its outside contour adjusts perfectly to the measurements of terminal boxes. The clear front panel of the terminal with light-emitting diodes for status display, plug-in contact labelling and detachable labelling fields guarantee clarity. The 3-wire system supplemented by a protective conductor terminal makes it possible to wire sensors/actuators directly.
Free mix of signals
The Beckhoff I/O system supports about 400 Bus Terminals and is thus probably the most comprehensive system on the market. The components enable users to operate mixed signal configurations without restriction at each station. This means that a single non-central input/output node can map all the necessary signals.
Appropriate Bus Terminals are available for any digital or analog automation signal type, for currents and voltages with standardised signal levels and for PT100 and thermocouple signals. Intelligent devices can be connected via Bus Terminals with serial interfaces in accordance with RS232, RS485 or 20 mA TTY.
The fine granularity of the Bus Terminals enables bit-precise composition of the required I/O channels. The digital Bus Terminals are available as 2-, 4-, 8- or 16-channel terminals. In the 16-channel variant, digital input and output signals are arranged in an ultra-compact way within a standard Bus Terminal housing across a width of only 12 mm. The standard analog signals of ±10 V, 0 V…+10 V, 0…20 mA and 4…20 mA are all available as 1-, 2-, 4- and 8-channel variants within a standard housing. In the 8-channel variant, analog input and output signals are arranged in an ultra-compact way within a standard Bus Terminal housing across a width of only 12 mm. The system is thus highly modular and can be projected cost-effectively with an accuracy down to a single channel.
The KMxxxx terminal modules with plug-in wiring combine 16, 32 or 64 digital I/Os within a very small space and with high packing density.
Economical and small
For the user, Beckhoff Bus Terminals offer independence from the particular fieldbus and terminal block design. Digital and analog signals can be mixed without restriction, starting with one or two signals per terminal. Beckhoff Bus Terminals replace manufacturer-specific designs and all the intermediate terminal positions. The Bus Terminal ensures transparency and flexibility. Distributors and terminal boxes become smaller, more economical, and in some cases can be omitted. Plants and machinery equipped with Beckhoff Bus Terminals offer significant competitive advantages.
