Stahl Compiles Oil-Rig Camera-Surveillance Package Stahl has compiled a scalable package of cameras and recording systems for camera surveillance in hazardous areas on gas and oil rigs. In addition to making operations safer, it enables users to carry out a thorough study of causes and fix any problems in the case of incidents. The system supports live monitoring at HMI stations and complete documentation of events. The standard package includes four cameras whose video signals can be recorded manipulation-proof for up to ten days. This network-compliant solution, which also permits authorised remote access to images via the internet, can be expanded to include twice or four times as many cameras. The recording capacity, which as a standard is covered by a 500GB hard disk, can be easily expanded to meet a specific application's requirements. Resolutions of up to 4 CIF, as well as a full PAL format with 704 x 576 pixels, can be selected for the H264 compressed digital-video file...

Stahl Releases Fieldbus Power Supply System Stahl has expanded the ISbus range, adding a modular Fieldbus power supply system that provides up to 28V and 500mA for Foundation Fieldbus H1 segments, and allows for redundant supply. In Boost mode, a parallel connection of two power supplies enables users to continuously supply the bus with up to 1A, providing sufficient power reserves even for special Fieldbus applications. An integrated basic diagnosis function monitors each segment for line faults, reporting these via a potential-free relay contact and indicating them via a red Error LED. The activation of the integrated switchable Fieldbus terminator is clearly indicated by a yellow LED. The units can be installed on a DIN rail or clicked into place on special bus carriers. On each bus carrier, up to eight segments with a standard supply or four segments with a redundant supply are connected to a host via optional precon-figured system cables. The bus carrier can be operated with...
