The 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.
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.
