The PI/NI-2D/24 and PI/NI-2I/I non-incendive barriers are designed to remove the need for bulky and costly explosion-proof or purged enclosures, sealed conduits, glands and fittings that are typically used in Class I, Division 2 areas.
The non-incendive barrier modules limit energy to safe levels,
preventing the risk of arcing or sparking, while allowing live wiring
on the device in a Class I, Division 2 or Zone 2 area. The PI/NI-2D/24
protects 24V digital signals in the event of a short circuit or
over-voltage condition. The PI/NI-2I/I limits the maximum short circuit
current to 24mA in 4-20mA loops. It can be installed with two-wire
4-20mA transmitters. Both analog and digital signal modules have two
channels and can use the Interface T-Bus connection system. The analog
module can be powered from the T-bus, but the digital module does not
require power. Phoenix Contact Inc.www.phoenixcontact.com800.322.3225
