INTRODUCTION
COMPONENTS
D12 ToxicTransmitter
TheD12 ToxicTransmitterisused to monitorforgasleaksnearstorage cylinders,process piping, or
gasfeed equipmentin virtuallyanytype ofindustrialplantenvironment. The transmitterhousingis
explosion proof, and israted forusein hazardouslocations(see specifications).The transmitterfeatures
an H10 Smart Sensor,a non-intrusive fourbutton userinterfacewith a back-lighted graphicsdisplay,
three levelalarmsystemwith three (optional) alarmrelays, high-resolution 4-20mA currentloop
output, real-time clock, data-logger, and optionalHART™orModbus™ communication interface. In
addition, the transmitteroffers severaloptionalH10gasgeneratorsforautomatic,timed testingofH10
sensors.
H10 Smart Sensorand C18 GasGenerator
H10 Smart Sensors and C18 generatorscontain non-
volatile memoryto storeinformation aboutthe targetgas
theywere designed to monitor, orgenerate. Theycontain
generalinformation aboutthe targetgas, such asthe name,
range, units,alarmsettings,alongwith specific calibration
information, such asresponse to gas, mA-Hrofusage, and
calibration history. Information istransferred intothe
transmitteratstartup,and wheneverone ofthe
componentsisinserted intoa live transmitter. Because all
calibration dataisstored inthe memory, sensormodules
maybe calibratedusinga sparetransmitterinthe shop,
and subsequentlyinstalled into a fieldtransmitter,
eliminatingthe need forfield calibration.
Sensorsandgeneratorsplug into the externalhousingat
the base ofthe transmitter. Theyare easilyremoved, and
installation issimplified bywayofmolded carrierthat
alignseach connectorfora perfectfit. Once installed,a ¼
turnlockingringsecuresthe carrierin place. Simply
installthe sensorand generatorintothe carrier(1),slide it
ontothe alignmentpins(2),and twistthe ring¼ turn
counterclockwise (3).
Sensorsandgeneratorsaredesigned forusein ambientair
attemperaturesof-30°to +60°C, ata relative humidity
between 20 and 98 %RH (some sensors are rated to -40°
C, oxygen sensors areratedto -10°C). Figure 1.Transmitter,sensor, generator

ELECTRICALCONNECTIONS
BoardStack
Thetransmitterconsistsoffourcircuit boards, knowncollectivelyasthe “stack”. Fromtop to bottom,
theyarethe, Display, CPU, Isolation, and PowerSupplyboards. The topthree boards, Display, CPU,
and Isolation, arefastened togetherwith metalstandoffs, and pluginto the PowerSupplyboard, which
isfastened tothe lowerhousingwithsimilarmetalstandoffs. Since mostexternalwiringconnections
are made toterminalson the PowerSupplyboard, itwillbe necessaryto remove the top three boards.
Toremove the top boards,unscrewthe transmitterhousingcoverand turn off the powerswitch, SW5,
located atthe 12 o’clockposition on the CPUboard. Graspthe outeredge ofthe metalfaceplate
coveringthe Displayboardand gentlyrockit side toside, while pullingitup, andawayfromthe
housing. Once the top boardscome free, liftthemoutand disconnectthe sensorribbon cable(note:this
connectoriskeyed foreaseofreconnectinglater).
Figure 7.Separatingthe boardstack
Please be aware of the hiddenribbon cable thatconnects the top
three boards to the sensor. This cableis justlong enough to permit
the top boards to comefree from the housing, but no further.
SetswitchSW5 to OFF before removing the upperboardstack from
the transmitter. Since SW5 does not disconnectpoweratthe
terminals of the PowerSupplyBoard,declassifyhazardous areas
priorto opening the transmitterhousing.

PowerSupplyBoardConnections
Electricalconnectionsaremade to terminalblockson the PowerSupplyboard. Power, currentloop,
(optional)digitalcommunications,and remote alarmreset, are connected atTB1. Connectionsto the
three (optional) relaysaremade atTB2.
Currentloop operation requires12-30 VDC powersupplied on the mA(+)terminal, fromwhich the
transmittersourcesa 4-20mA currentloop outputsignalon the mA(-)terminal. The transmittercan
operatefromcurrentloop poweralone, butwithoutrelays, LCDbacklighting, andRS232/RS485
communications.
Loop-powered operation requiresa
maximumcurrentof25 mA, while
transmitters wired in3-wire mode
will require a maximumof250
mA, with all relaysactive. Power
suppliesoperatingmultipleunits
should be sized fortwice the
calculatedcurrentrequirementto
allowforstart-up inrushcurrent
requirements.
Figure 8.PowerSupplyBoardConnections
Thetransmitterhaslimited spaceforwire;therefore, use the smallestgauge wireavailablethatis
compatible with electricalcode and currentrequirements. When poweringa groupoftransmitters in 3-
wire mode fromthe same powersupply, 12 AWGwireisrecommended forlongruns, with dropsof
highergauge wireto each transmitter.
Internalrelaysarebestusedaspilotrelaysif heavy load switchingisdesired. Use suitable arc
suppression devicesacross loadsswitched through internalrelays.
Thetransmitterhousingisnormallygrounded through explosion proofconduit. In the absence ofsuch
conduit, use a suitable groundingstrap to bond the transmitter’s housingto earth ground.
Alwaysfollowwiring practicesgoverned by local, state,and nationalelectricalcodes.

ATIA17/B14 Monitor(s),3-Wire Mode
D12 transmitters maybe connected in 3-wire mode toan ATIA17/B14 receiversystem. In 3-wire
mode, transmitterswill include alarmrelays, LCDbacklighting, and RS232/RS485 communication
options. Consultthe A17 PowerSupplyand B14 ReceiverModule O&Mmanualsto properlysize the
systempowerrequirements.

Power Only,NoOutputOptions
Ifthere are no outputoptions, transmitters maybe powered froma single, primarysupplyasshown.
Size each powersupplyaccordingtothe numberoftransmitters,the currentdemand ofeach (see
specifications), and the wire resistance. The wire resistance mustnotbe allowed to drop the primary
supplyvoltage below12Vatthe primarysupplyterminalsofanytransmitter. Hint: Ifpossible, use 12-
14 AWGwire on primarysupplyconnections(shown in bold), keep the numberoftransmitters low,
and verifythe voltage on the on the transmitterfurthestfromthe supply.

CurrentLoop Receiver,DualSupplies (4-Wire Mode)
Toreduce the powerrequirementofa singlecurrentloop supply, the transmittermaybe powered from
both a primaryand loop supply, providingthe followingconditionsare met.
1. Supplygroundsare directlyconnected to minimize ground loops, and,
2. ThePrimarySupplyVoltage isatleast12V, and mustbe equalto, orexceed, the Loop Supply
Voltage, asmeasuredatinstrumentterminals.
Size each powersupplyaccordingtothe numberoftransmitters,the currentdemand ofeach (see
specifications), and the wire resistance. The wire resistance mustnotbe allowed to drop the Primary
SupplyVoltage belowthe Loop SupplyVoltage, which mustbe atleast12V, asmeasured atthe
terminalsofanytransmitter. Hint:selecta PrimarySupplywitha highervoltageoutputthan the Loop
Supply, and use 12-14 AWGwire, if possible. Keep the numberoftransmitterssupplied bythe
PrimarySupplylow, and verifythe voltagesatthe terminalsofthe transmitterfurthestfromthe Primary
Supply.

HART Transmitter,Point-to-Point(2-Wire)
TheHART“Point-to-Point” connection permitsthe transmittertocommunicate digitally, while
retainingthe functionalityofits4-20mA currentloop. Settingthe transmitter’s pollingaddressto0
permitsthe currentloop to functionnormally. Accordingto HARTspecifications,the currentloop
mustbe terminated witha load resistorbetween 230 and 1100 ohms;however,transmitter
specificationsrestrictthe maximumanalogoutputresistance toa lowervalue (see Specifications). The
term, “active source”, refersto atransmitterthatisnotloop powered, and sourcescurrentfrompower
applied toit onseparateterminals. Sizethe powersupplyaccordingtothe numberoftransmitters, the
currentdemand ofeach transmitter(see specifications), and wireresistance. Wire resistance mustnot
be allowed to drop the PrimarySupplyVoltage below12Vatthe terminalsofany transmitter. Hint:
use atleast14 AWGwire on supplyconnections(shown in bold).
