FAQ
What is the XP95 I.S. Galvanic Barrier used for?
The XP95 I.S. Galvanic Barrier is used for intrinsic safety applications where fire and smoke detection is required in hazardous areas. It provides a safe interface for control and signal transfer to XP95 compatible alarm transmitters operating inside potentially explosive atmospheres, ensuring reliable fire detection whilst maintaining intrinsic safety requirements.
Does the barrier require a separate power supply?
No, the XP95 I.S. Galvanic Barrier is loop-powered, which means it draws its power from the fire alarm control loop itself. This eliminates the need for separate power supplies and simplifies installation. However, it’s important to verify using the technical data that proper voltage is available to the field devices.
What safety certification does the barrier hold?
The XP95 I.S. Galvanic Barrier achieves Safety Integrity Level 3 (SIL3) certification according to IEC 61508, representing the highest level of safety performance for single-channel devices. It also holds ATEX certification for European markets, IECEx approval for international applications, and FM/UL approvals for North American installations.
What hazardous area zones is the barrier approved for?
The barrier is approved for use in Zone 0, Zone 1 and Zone 2 hazardous gas atmospheres, as well as dust environments. It carries the marking [Ex ia Ga] IIC for gas and [Ex ia Da] IIC for dust applications, making it suitable for the most stringent hazardous area classifications where continuous or frequent explosive atmospheres may be present.
How is the XP95 I.S. Galvanic Barrier installed?
The barrier is designed for simple installation on standard 35mm DIN mounting rail according to EN 60715:2001. It features removable screw terminal connections for field and control circuits, with clear terminal identification. The compact dimensions of 20 x 107 x 115 mm allow for space-efficient installation in control panels and junction boxes.
What is the operating temperature range?
The XP95 I.S. Galvanic Barrier operates reliably across an ambient temperature range of -20°C to 60°C (-4°F to 140°F), making it suitable for both indoor and outdoor installations in various climatic conditions where hazardous atmospheres may exist.
