Belden CDT introduces new cables for Process Automation applications

At Interkama+ in Hannover, Germany, Belden CDT introduced three new ranges of Process Automation (PA) cables for use in instrumentation, regulation and control technologies in key industries including the oil & gas industry, chemical processing, paper & pulp manufacturers and processors and the metals industry.

The new ranges are

- 7000x series of Profibus PA cables for process automation

- LSNH & LSNH/armoured Devicenet cables

- Circuit integrity PLTC cables complying to UL and IEC standards

7000x series of Profibus PA cables for process automation

The Belden CDT new 7000x Series is aimed at process automation systems designed by Siemens for the processing industry. The range includes 2 PVC versions, an LSNH version and an LSNH/SWA (Steel Wire Armoured) version.

These cables meet all requirements of IEC 61158-2 Fieldbus for use in industrial control systems and are suitable for use in hazardous areas zone 1 and 2, group II, as defined in IEC 60079-14 or class I or class II division 2 as per NEC 501.4 (b) or NEC 502.4 (b). All versions are oil resistant and are suitable for use in demanding industrial environments. Other jacket options such as PUR or Teflon or different armouring options such as steel wire braid are available upon request.

LSNH & LSNH/armoured Devicenet cables

The new Belden CDT halogen free versions of DeviceBus® cables are suitable for use in ODVA Devicenet™ networks. These cables are completely halogen free and meet IEC 60332-3-24 standards. The LSNH versions may be used for indoor and outdoor applications and at low temperatures of up to -45˚C. For enhanced mechanical protection and/or rodent protection, Steel Wire Armoured versions are available as are other jacket options such as PUR or Teflon or different armouring options such as steel wire braid. UL and ODVA approvals are pending.

Circuit integrity PLTC cables complying to UL and IEC standards

New Belden CDT 300 V instrumentation cables meet the UL 2196 and IEC 60331 standards for circuit integrity, which is very important in the processing industry, to prevent loss of assets in the event of a fire. These cables can be used in the emergency shutdown system as well as in the gas / fire detection systems. The standards prescribe the minimum time which the cables will have to withstand, UL 2196 2 hrs rapid temperature rise fire starting at 538˚C (1000˚F) to 1010˚C (1850˚F) and IEC 60331 calls for a 3 hr burn test at 750˚C during which time the insulation is not allowed to fail. These cables are standard halogen free and are suitable for in and outdoor applications as well as for use in hazardous areas zone 1 and 2, group II, as defined in IEC 60079-14 or class I or class II division 2 as per NEC 501.4 (b) or NEC 502.4 (b).

All these new products complement the full range of Belden CDT Profibus PA cables and Halogen Free Devicenet cables. According to Erik Holswilder, Market Manager Industrial EMEA at Belden CDT, they meet the wide variety of requirements in instrumentation, regulation and control technologies: "Process Automation is used extensively by heavy industries who manufacture in continuous process. Over the years, pneumatic systems have migrated to 4- 20 mAmp systems and proprietary solutions - and today they use open digital systems. The Belden CDT range of Process Automation cable solutions offers cost, quality and performance benefits to everyone in the value chain: manufacturers, global companies with assets in multiple countries, Main Instrument Builders (MIVs) and EPC contractors."
