POSITAL introduces improved PROFINET I/O encoders which, according to the V4 profile, support IRT, RT and NRT data transfer (isochronous real-time/real-time/non-real-time). The revised encoders feature an Ertec200-based platform and reach cycle times as low as 1 ms (IRT) and 10 ms (RT). They are parameterised via the control system and configuration is facilitated by a GSDML device file.

Versatile And Convenient Installation

With a diameter of merely 58 mm, the devices are very compact. A connection cap is not necessary. Unlike Profibus models, the encoders do not require terminating resistors or switches for address allocation. Being shorter than most Industrial Ethernet encoders on the market, they can be used in applications with limited installation space. The encoders are available as hollow and solid shaft versions. They feature an integrated IRT compatible switch which facilitates wiring and allows users to save expenses for external hardware.

For a Wide Range of Applications

Like all OPTOCODE encoders, the PROFINET I/O models use a proven opto-electronic scanning method to record position values. The single-turn sensor provides a resolution of 16 bit per revolution. Additionally, a maximum of 16.384 revolutions (14 bit) can be registered in multi-turn mode, thereby covering a measuring range of 30 bit. The encoders are suitable for use in e.g. automotive body construction, packaging technology or standard machine construction applications. Migration of existing Profibus systems to the new standard is easily possible, since the device profile management has been retained. Further equipment includes two M12 connections for data transfer, one M12 connection for voltage supply, and six LEDs for bus diagnosis. Designed for a -40...+85 °C temperature range, the units provide IP67 protection on the housing side and IP64 on the shaft side (an optional sealing ensures IP67). All OPTOCODE encoders operate without backup batteries and instantly provide current absolute position values without referencing even after power failure.
