September 18, 2009 -- Belden announced added temperature and use ratings, and expanded multi-pair capabilities to its line of low capacitance DataBus cables for Foundation Fieldbus applications. The company's DataBus cable line consists of PLTC/ITC-ER, PLTC and TC-ER versions that are specially designed to meet Fieldbus specification IEC 61158.2 (ISA/SP-50).

Fieldbus is an all-digital, serial, two way communications protocol that standardizes the interconnection of field devices at a communications rate of 31.25 kilobytes per second (Kb/s). Belden says its DataBus cables offer superior electrical design and robust construction to ensure consistently reliable performance, while also providing installation flexibility in diverse industrial environments, including outdoor installations and sites requiring multiple or extended cable runs.

Additions and enhancements to Belden DataBus Cables for Foundation Fieldbus applications include:

* Product No. 3076F -- Type A, 300V single pair with Beldfoil shield, NEC: PLTC ITC-ER, CMG, CEC: CMG FT4. Extended temperature ratings to -400C Cold Bend (per UL 1581), and CMX rating for outdoor use as well as direct burial rating. IEEE 1202/383. IEC 60332-3-24 (Cat C). Also available in a continuous aluminum armor version, part number 183076F. Other interlocked armoring options also available.

* New Product No. S1359A -- Type A, 300V 50-pair individually and overall shielded Fieldbus cable with a sunlight- and oil-resistant PVC jacket NEC: PLTC, ITC, CMG. CEC: CMG FT4. IEEE 1202/383. IEC 60332-3-24 (Cat C).

The Belden DataBus cables are appropriate for use in all Class1, Div. 2 applications. They are also RoHS compliant and CE approved.
