Model 2110EX-A Explosion Proof Housing
CHARACTERISTICS
General Desription:
The Model 2110EX-A is NRTL certified explosion proof for use in hazardous
locations/environments (Class I, Division 1, Group D) in accordance with UL1203, UL61010-
1, CSA C22.2 No. 30, and CSA C22.2 No. 61010-1. The device is also certified to provide
Intrinsically Safe output for use in hazardous locations (Class I, Division 1, Group D) in
accordance with ANSI/UL 913, CSA C22.2 No. 60079-0 and CSA C22.2 No. 60079-11.The
Barrier Unit actively limits the current and voltage to protect intrinsically safe equipment from
power spikes and to maintain the intrinsic safety. The barrier provides intrinsically safe power
and intrinsically safe power and communication or I/O lines for devices located in Hazardous
Areas.
Functions:
The 2110EX-A is capable of delivering safe levels of supply power and 2-wire RS485 digital
signals to a device located in Class I Division 1 location and also provides two 4-20mA(3 wire
configuration) analog signal output channels.
SPECIALWARNINGS
Use only NRTL – listed NEC Class 2 power supply. Voltage should not exceed 24VDC
Use only with certified Explosion Proof conduit or certified Explosion Proof cable and
connector (eg. CLX and TMCX products).
Always attach the cables to the connector strain relief plate with cable ties. This will
ensure that cables do not migrate in the enclosure if they are disconnected from connector
by accident.
Always lock the cover by fastening its hex screw with a hex socket; use a hex spanner of
1.5mm.
AVERTISSEMENTS SPÉCIAUX
N'utilisez que des blocs d'alimentation limités NEC class 2 répertoriés d‘une Laboratoire
d'essai reconnu à l'échelle nationale. La tension ne doit pas dépasser 24VDC
Utilisez uniquement des conduits certifiés antidéflagrants ou des câbles et connecteurs
certifiés antidéflagrants (par exemple, les produits CLX et TMCX).
Fixez toujours les câbles à la plaque de décharge de traction du connecteur avec des
colliers de serrage. Cela garantira que les câbles ne migreront pas dans le boîtier s'ils sont
déconnectés du connecteur par accident.
Verrouillez toujours le couvercle à l'aide d'une vis à six pans creux à l'aide d'une clé
hexagonale de 1,5 mm de diamètre.
