New: Rugged bus cables for process automation networks


networks, instrumentation, control components

Northwire offers the DataCell Field Profibus PA and other rugged cables for use with industrial networks, serving process control and machine control applications.

Networked process automation networks may get a boost in reliability with Northwire Inc. DataCell Field rugged bus cables for Profibus PA . An Arctic-rated marine shipboard version suitable for use down to -55 °C is also offered. It is ISA/SP50 Type A cable available in 18 AWG, with foil shielding. It is rated for CSA CMX-Outdoor-CMG and FT4.

DataCell Field Profibus PA also is rated for ITC (instrument tray cable)/PLTC (power limited tray cable) exposed-run (ER) applications, allowing users to eliminate the conduit when the cable is installed in accordance with recent National Electrical Code (NEC) amendments. In 2002, the NEC was amended to allow exposed runs of certain tray cable and PLTC. This code change is advantageous because metal-clad cable or conduit is no longer required, resulting in significant material and installation cost savings.

Northwire ITC/PLTC cables are approved for use in Class 1 and 2, Div. 2 hazardous areas. The cable's PVC jacket is resistant to oil, sunlight, ozone and water and is available in standard and custom colors. It is available in bulk quantities of 1,000-feet minimum and can be shipped in 10 days or less.

Other rugged cables for networks typically used in process applications include Foundation fieldbus H1 and HART Communication Foundation. Similarly rugged cables are available for discrete factory automation and control applications for ODVA, DeviceNet, Profibus DP, AS-interface, and CANopen. Northwire is based in Osceola, WI.

Samples of Northwire DataCell Field rugged bus cables are available free.
