Direct-reading Valve Control module uses photoelectric direct reading technology to read data word round, compared with the conventional pulse table, it can be reduced to zero reading error, AMR metering system is ideal zero error product. Module uses low-power design, usually no power supply, only when the meter readings and conduct valve switch its power needs. The module can be installed directly in the base table counter, assembled into remote base table VRLA photoelectric direct reading table, with the smart metering system equipment, complete intelligent reading copy cell data and remote meter control valve on / off, and Implementation and settlement center networking data sharing.


一、Features

1, reading the word round of data, compared with the conventional pulse table, it can be reduced to zero reading error;

2, low-power design, and only if the readings valve switch supplied with power;

3, the use of advanced data encoding and verification technology, high reliability communications;

4, in line with "electronic remote meter" (CJ / T 224-2012) standard;

5, compatible with a variety of communication protocols; DL / T645, CJ / T188 and internal protocols;

6, to meet the EMC, ESD, EMI and other electronic products, electromagnetic compatibility design requirements, to achieve industry-leading level;

7, combined with the host computer system, to establish a remote automatic meter reading management system, the real meter reading, monitoring automation.


二、Second, the technical parameters

2, working voltage: DC 36V;

3, the working current:

Current meter reading ≤9.0mA

Quiescent current ≤1.3 mA

Valve On / Off Bus Current ≤50 mA (reference value, the valve will be different depending on the difference)

Valve open / close valve motor input current ≤30 mA (reference value, the valve will be different depending on the difference)

4, the working environment: temperature: -10 ℃ ~ + 45 ℃ Humidity: 0 ~ 95% RH;

5, Storage temperature: -25 ℃ ~ + 65 ℃;

6, with the host computer communication: M-bus field bus;
