Kaitahuri raraunga HART raupapa PH-SM100-M

Hua Kupu Whakataki

Ko te kaitahuri raraunga HART raupapa PH-SM100-M he hua i whakawhanakehia mā te whakamahi i te tukatuka ARM, te whakarerekētanga me te tangohanga kawa HART ASIC, ā, he maha ngā whakamahinga mahi. Kua hangaia kia rite ki ngā whakaritenga o ngā hua ahumahi me te tino pono me te pumau. Kei te kohikohi raraunga he atanga RS 485 paerewa, he atanga RS 232 me te kuwaha, ka taea te tuku mārama ki te taputapu atamai me te kawa HART, te huri rānei ki te kawa MODBUS_RTU, MODBUS_TCP rānei hei pānui raraunga, kia pai ai te tuku raraunga i te wā tūturu.

E tutuki ana te kawa HART i te paerewa o Bell202 Frequency Shift Keying (FSK), ā, e whakarerekē ana i ngā tohu matihiko i runga i te 4~20mA, e ārahi ana i ngā taputapu kawa HART ki te whakawhitiwhiti raraunga taha-rua me te kore e whakararuraru i te tohu anaro o te 4-20mA. Ko ngā kaikohikohi rā HART raupapa SM100-M he mea hanga mō te whakarerekētanga me te tango i ngā tohu matihiko me ngā tohu anaro.

Ngā Āhuatanga o te Hua

● tautoko ki te hono 8 HĀT ngā taonga puoroi taua wā anō.

● tautoko te matawai whakarara i te wā kotahi o ngā hongere HART katoa i whirihorahia e te kaikohi raraunga HART.

● tte wehenga hikohiko-toru-mutunga i waenganui Kua oti ngā hongere HART me te pūtake hiko matua. E rua ngā waea e whakamahia ana e ia hongere, ā, kāore e iti iho i te 1500 V te ngaohiko wehewehe hikohiko o te waeine HART, e tautoko ana i te mahi wehewehe tohu HART /4~20.

● Atanga RS485, ko te ngaohiko wehewehe atanga NET Ethernet kāore i raro i te 1500 V.

● te tango i te hoahoa modular o te wehewehe i te module HART mai i rorohiko matua,ā, e tautoko ana i te mahi whakakapi i te kōwae HART ipurangi i roto i tētahi hongere.

● he rama tohu motuhake kei ia hongere hei whakarato ipurangi i ngā taputapu HART, hei tohu tūnga whakawhitiwhiti kōrero mō ngā taputapu HART.

● me te tohu tūnga taputapu: oma/hapa, atanga whakawhitiwhiti kōrero, me ētahi atu.

● te tere whakahou raraunga mō ia hongere

● tautoko i te atanga Ethernet (tere iti iho i te 100 Mbps) me te atanga RS485.

● tautoko i ngā tohutohu HART motuhake hei pānui i te HART ID o ngā taputapu HART katoa

● tautoko i te whirihoranga me te aratau whakahaere, tautoko i ngā tautuhinga mamao Telnet.

● e tautoko ana i ngā whakahōu pūmanawa mamao.

● tautoko i te tāutanga arataki DIN paerewa.

● kāore e pāngia te tuku tohu anaro me te tika o te 4~20 mA ina he noa te taputapu whakawetohia te hiko, te hē rānei o te mahi, ā, he iti iho, he ōrite rānei te ātete o te ara iahiko ki te 250R.

● kāore tēnei taputapu e tuku hiko ki ngā taputapu parae.

● Putanga 5.0. Kawa HART Hototahi
