Description
Discrete Non – Incendive Barriers are used for Hazardous Locations.
This module is designed to provide isolation to enable circuits beyond the module to be rated as
non-incendive. It is typically used on “discrete” inputs to PLC’s to allow the use of non-explosionproof wiring and end devices in Class I Division 2 Groups, A, B, C and D Hazardous Locations. The barrier is suitable for use with all gases when located outside of the hazardous location and with gases having ignition temperatures of 160o C or higher when located in the Class I Division 2 Hazardous Locations. The barrier must be located in an enclosure suitable for the location. The use of a weatherproof enclosure is recommended when the barrier is located in the Hazardous Area.
Features:
Provides non-incendive isolation for circuits up to 24 VDC
Eliminates need for expensive explosion proof enclosures for End Field Devices
Eliminates costly wiring normally required in Class I, Division 2 locations.
DIN rail mountable terminal block style housing
Typical Applications:
Class I, Division 2 Locations in:
Oil Refineries
Gas Processing Plants
Oil and Gas Production Facilities
Petrochemical Plants
Pipeline Facilities
Sewage Treatment Facilities
