Middletown, PA - New non-incendive barriers from Phoenix Contact use current and voltage limiting circuitry to minimize the risk of ignition in hazardous Class I, Division 2 or Zone 2 environments. The I/O modules limit energy to safe levels, which prevents arcing or sparking and allows live wiring on the device in a Class I, Division 2 or Zone 2 area.

Phoenix Contact new non-incendive barriers

Two versions are available. The PI/NI-2D/24 protects 24 V 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 24 mA in 4-20 mA loops. It can be installed with two-wire 4-20 mA 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.
Non-incendive barriers 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.
