It is promoted by Siemens and by organized, interested and committed manufacturers and users in the PNO (Profibus user organiza- tion). The IP 20 interface on the device side is standardized as a 9-pin D-Sub female connector. The max. data transmis- sion rate is 12 Mbit/s. The cable is a shielded twisted pair conductor. The cable sheath is violet and the signal cores are green (A) and red (B). With its comprehensive program, ERNI provides customers with a wide variety of options. Particular emphasis should be placed on the different termi- nation technologies, from the traditional screw terminal to the cage clamp terminal to the IDC terminal.* Electrical and mechanical characteristics Interface connector D-Sub, 9-pin, male D-Sub male or female (PU connection) Class 2 D-Sub male reversed version Class 3 Cable termination 2 x horizontal, 2 x vertical, MAX: 2 x axial 1 cable outlet can be sealed with blanking plate Cable diameter 4.5 mm (0.177”) – 8.0 mm (0.315”) 2 2 Cross section of individual conductor Screw terminal: solid max. 1.5 mm ; stranded max. 1.0 mm IDC terminal: solid ø 0.64 mm 2 2 Cage-clamp terminal: 0.08 - 0.5 mm (0.75 mm ) Termination type Screw terminal, IDC terminal, cage-clamp terminal Data transmission rate According to bus specification, 12 MBit/s Temperature range -20 °C – +70 °C Permissible humidity Max. 75 % at + 25 °C, non-condensing Protection class IP 40, MAX: IP 30 Housing material Thermoplast UL94V-1, MAX: ZnAl, galvanized D-Sub screw #4/40 UNC, knurled with cross-head UL approval UL E84703 * CE marking ERbic connectors are passive components and do not need to be identified with the CE marking according to EU direc- tives. * Due to continuous advancement, it is possible that the UL approval of a new version may not have been completed at the time of going to press.

Catalog E 074441 01/06 Edition 4 www.erni.com 11 ERbic Profibus Ex i There is a special Profibus specification for safety-orientated intrinsically safe applications. Intrinsic safety is achieved by limiting the energy. At low voltage, this is reflected, among other things, by a higher current density in the bus line, as the devices are also supplied with power via the bus line. With regard to the connector, the main factor is compliance with EN 50020. For example, defined clearance and creepa- ge distances and current carrying capacity must be taken into account. These Ex i connectors have been developed in coo- peration with ABB and approved for their S900 controller. The individual connector alone does not require separate appro- val. This must always be given in conjunction with the system in accordance with the relevant directives and standards.

Catalog E 074441 01/06 Edition 4 www.erni.com 13 ERbic CAN Bus The CAN bus, originally developed for automobile engine management, is distinguished by its particularly high relia- bility. Among other things, this necessitates a more compli- cated protocol, which leads to lower data rates and cable lengths. This can be compensated for in part by larger cable cross sections. Data rates reach 1 Mbit/s. The 9-pin D-Sub connector is standardized as the interface to the device. In some cases, a version with a shield coupling capacitor is available as an option (cable shield <-> housing D-Sub).
