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.

CURRENT LOOP 1 and 2 SCALING
Current loop 1
Current loop 1 is dedicated to communicate DLS2100 sensor top level (usually product level for
oil and gas industrie). The scale for this loop is set at the device start up when 2110EX-A read from the
DLS2100 level sensor the following parameters
-min_4mA – level for supplying 4 mA in the current loop, usually 0
-max_20mA – level for supplying 20mA in the current loop, usually maximum level that DLS2100
can monitor
The current in the loop for a random level (top) is given by:
I1 = (20mA - 4mA) * top / (max_20mA-min_4mA),
where I1- loop current in mA
top – top level in inches.
Current loop 2
Current loop 2 is dedicated to communicate DLS2100 sensor bottom level (usually interface level
for oil and gas industrie) or the temperature according to J6 jumper setting(see Table 6 above).
If J6 is set for bottom level the scale for this loop is set at the device start up when 2110EX-A read
from the DLS2100 level sensor the following parameters
-min_4mA – level for supplying 4 mA in the current loop, usually 0
-max_20mA – level for supplying 20mA in the current loop, usually maximum level that DLS2100
can monitor
The current in the loop for a random level (bottom) is given by:
I2 = (20mA - 4mA) * bottom / (max_20mA-min_4mA),
where I2- loop current in mA
bottom – bottom level in inches.
If J6 is set for temperature the scale for this loop is set for the range 0°F to 200°F (4mAcurrent means
0°F and 20mA means 200°F).
The current in the loop for a random temperature temp is given by:
I2 = (20mA - 4mA) * temp / 200,
where I2- loop current in mA
temp – temperature in °F.

EXA - model 2110EX-A
MM – manufacturing month;
YY – manufacturing year;
nnnnn – 5 digits incremental number;
EXA022200101 represents a 2110EX-A model device manufactured in February 2022 and having the
assigned order number 00101.
The serial number will be clearly printed on the enclosure label.

STEP BY STEP INSTALLATION INSTRUCTIONS
1. Check device for proper model and voltage
a. Review the model number on the attached label to ensure you are using the analog
version of the Explosion Proof Housing. The Model should be 2110EX-A.
2. Loosen the nut on the top part of the 1-inch union, until it is almost removed.
3. Ensure the number of sensor connector pins match the number of 2110EX-A connector pins.
Sensor connector with 6 pins 2110EX-A connector with 6 pins
4. Apply thread sealant to the 1-inch NPT connector on the sensor.
5. Hold the 2110EX-A above the sensor flange connector with one hand; insert and tighten up the
connector to the sensor with the other hand.

Tighten connector
6. Unscrew the bottom part of the union from the 2110EX-A. Then screw the bottom part of the
union‘s 1-inch FNPT onto the sensor‘s 1-inch MNPT flange until hand tight. Make sure the
connector cable is not caught in the threads or joint. Tighten the union using a 1.5“ wrench but
do not overtighten.
Ensure cable is not caught in threads or joint
7. Screw together the union parts until hand tight. Make sure the threads are straight to avoid
thread damage. Use a 1.5“ wrench to hold the threaded adapter (bottom part of the union) and a
2-1/16 “ torque wrench to tighten the union nut to 125 ft. lbs.
Tighten connector
8. Connect the current loops and power wires to the orange connector X1 according to the control
drawing 2110EX-A-002 following the pinout that is marked on the circuit board. The wire
size should be in the range 14 to 28 AWG. Secure the wires on the pull tab using a cable tie.
9. Seal the incoming conduit with a certified EX fitting within 18 inches from the 2110EX-A
enclosure.
