D1xB2LD2 Explosion Proof LED Multi-function Beacon 1-21-206

Description

The D1xB2LD2 beacons produce a high output LED flash required for effective signalling in environments with elevated levels of ambient light. The field replaceable colour filter enhances the strobe and is constructed from UV stable PC. The robust enclosure features a threaded flame path, four cable entries. Mounting options include surface via integrated lugs, pendant or by addition of optional multi direction stainless steel bracket. SIL1 & SIL2 Route 2H compliant to IEC61508 (2010) as standard.
