By providing electrical barrier between control devices and equipment installed in hazardous (Class 1, Division 2) environments, fuse-protected ASD-NIB Series minimizes risk of ignition on load side. This enables standard wiring practices to be used for in-field connections and eliminates need for explosionproof enclosures/conduit. At 6.2 mm wide, this non-incendive, CCSAUS-approved barrier module connects single-channel analog or discrete signal wires from 24–12 AWG.
