A'oa'o pe fa'apefea ona fa'apipi'i ma fa'apolokalame le PCL-2 Pulse-to-Current Loop Converter with Solid State Instruments 'pepa fa'atonuga. O lenei suiga tele e mafai ai ona maua le 4-20mA galuega faʻatatau i le faʻaogaina o fua o eletise, vai, poʻo kesi. Fa'afaigofie ona fa'ae'e i so'o se tulaga ma fa'afeso'ota'i i se fa'atulafonoina + 24VDC Loop Power Supply mo le fa'atinoga lelei.
A'oa'o pe fa'afefea ona fa'apipi'i ma fa'agaoioi le WPG-1 fa'ainitaneti pulse generator i la matou pepa fa'atonuga. E fetaui ma mita eletise AMI e mafai e WiFi, o le WPG-1 e faigofie ona faʻapipiʻi ma faʻamalosia e AC voltagu. Su'esu'e atili e uiga i lenei meafaifa'aili malosi e maua ai laina fa'atosina o le pulusi mo le sili atu le lelei.
A'oa'o pe fa'apefea ona fa'atulaga lelei ma fa'aoga le SOLID STATE INSTRUMENTS MPG-3 Metering Pulse Generator. O lenei tusi lesona o loʻo tuʻuina atu ai faʻatonuga taʻitasi i luga o le faʻapipiʻiina, faʻaogaina o le eletise, ma faʻamatalaga faʻamatalaga mo le faʻatinoina lelei. Lelei mo i latou o loʻo galulue faʻatasi ma afi afi ma mita, e pei o le MPG-3.
A'oa'o pe fa'afefea ona fa'apipi'i lelei ma fa'afeso'ota'i le CIR-22PS Customer Interface Relay ma lenei tusi fa'atonuga. Mai le tulaga fa'apipi'i i le fa'aogaina o le eletise, o lenei ta'iala e aofia uma ai. E fetaui lelei ma le eletise eletise po'o le malo malosi o le pulupulu amata, o le CIR-22PS o lo'o fa'aalia ai le sapalai o le eletise mai le 120V i le 277VAC. Seti osooso J1 ma J2 mo le fa'aoga sa'o o totonu -- pe A po'o le C.
A'oa'o pe fa'afefea ona fa'apipi'i lelei ma fa'afeso'ota'i le Solid State Instruments CIR-13PS Customer Interface Relay ma lenei fa'amatalaga fa'aoga tusi lesona. O lenei feso'ota'iga feso'ota'iga ua mamanuina mo 2-Wire po'o le 3-Wire mea fa'aoga ma fa'aalia ai le fa'aogaina o le eletise. Maua fa'atonuga ta'itasi mo le fa'apipi'iina ma le uaea, fa'apea fo'i ma fa'amatalaga e uiga i ana galuega e tolu-uaea e tolu.
