Kev tsis

WB1925B35 (Ib qho Khoom Siv Hluav Taws Xob Channel Ib Thaj Tsam Hloov Tam Nrho Tam Sim No) tau xaiv cov duab hluav taws xob tsis sib xws thiab tshuab txais digital thiab cov ntaub ntawv thev naus laus zis los sau thiab suav DC cov cim tam sim no thiab DC qhov ntsuas hluav taws xob nyob rau lub sijhawm, thiab cov ntaub ntawv tawm hauv RS485 hom tsheb npav. Cov khoom lag luam' s DC tam sim no thiab DC qhov ntsuas hluav taws xob cov lus taw qhia, cov zis thiab cov khoom siv hluav taws xob sib cais tau sib cais tag nrho, me me qhov loj me, lub teeb hauv qhov hnyav thiab yooj yim rau nruab; nws tuaj yeem siv dav hauv ntau qhov kev tswj hwm tsis siv neeg los mus sau cov sib txawv DC tam sim no thiab DC qhov ntsuas hluav taws xob rau ntawm qhov chaw Nws khaws A / D ntim ntawm lub kaw lus thiab muab cov software hloov kho yooj yim thiab kho vajtse rau lub system.

Nco tseg: IN1 txuas nrog DC voltage nkag, IN2 txuas nrog DC voltage input, thov them sai sai rau qhov polarity ntawm cov teeb liab tawm tswv yim; + E thiab GND txuas nrog lub zog ua haujlwm ntawm qhov khoom; 485A thiab 485B yog txuas nrog lwm cov ntu tsis muaj kev txwv ntawm RS485 cov khoom siv davhlau ya nyob twg.

Kev siv raug ntawm cov ntsuas

1. Real-time cov ntaub ntawv tso zis tawm ntu (siv cov qauv kev sib txuas lus ntawm Modbus-RTU)

Thaum lub sensor tau txais" nyeem cov ntaub ntawv (03)" kev hais kom ua los ntawm tus neeg siv' s tus tswv tsev computer, nws tsim tawm cov ntaub ntawv hauv kev txiav txim hauv qab no:

Tsis yog	Sau npe chaw nyob	Cov Ntsiab Lus	Lub ntsiab lus	Bytes
1	0	U	IN1 DC Voltage	2
2	1	I	IN2 DC Tam Sim No	2
3	2	P	DC fais fab	2
4	3	EH	Lub Zog Hluav Taws Xob	2
5	4	EL	Tsawg Zog Hluav Taws Xob	2

Nco tseg: Lub sensor tuaj yeem xaiv cov khoom siv tawm raws li cov neeg siv' s xav tau. Txoj kev hais tawm ntawm cov zis tawm tau teev nyob rau hauv Cov Lus Sib Txuas Lus.

2. Cov zauv suav kev ntsuas

Hauv qab cov lus hauv qab no, Rx yog qhov nuj nqi uas xa rov qab los ntawm kev tso npe. Umax1 qhia tus nqi ntsuas ntawm IN1, thiab Umax2 qhia tias tus nqi ntsuas ntawm IN2. Saib cov npe khoom lag luam rau ntawm cov nqi ntsuas;

Yog tias tam sim no shunt txuas nrog rau pem hauv ntej kawg ntawm cov lus qhia tam sim no, Ix yog cov kev cai tsim tawm ntawm shunt.

Daim phiaj, lub neej ntawd yog 1 yog tias tsis muaj shunt.

Parameter npe	Xam txheej txheem	Cov hom ntaub ntawv	Cov ntsiab lus tsis yog
Kev tsuj roj	Rx × Umax1 × Ix × 0.0001	Xee tus lej them	U
Tam Sim No	Rx × Imax2 × Ix × 0.0001	Xee tus lej them	I
Lub Zog	Rx × Umax × Imax × Ix × 0.0001	Tus lej tsis kos npe	P
Lub Zog Hluav Taws Xob	Rx × Umax × Imax × Ix × 0.0001 (WH)	Tus lej tsis kos npe	E

Daim ntaub ntawv:

Kev txawj ntse tsawg hluav taws xob faib hluav taws xob;

DC fais fab npo, lub thawv hloov chaw;

Qhov ntsuas kub thiab ntsuas hluav taws rau kev hloov pauv, tua hluav taws rau cable;

High-voltage switchgear fiber optic ntsuas qhov ntsuas kub;

Transformer tiv tauj xyuas.
