1 Product Overview

SC-GP-IR LAN Ethernet infrared meter reader is a product launched by Shanghai Shucai IoT Technology Co., Ltd. for the DLT645 to JSON function of electricity meter collection . It automatically collects data from DLT 645 meters, converts it into JSON format and sends it to the cloud server. It supports 1 Ethernet interface and RS485 serial port. The high-quality power supply design with a wide voltage of 9~24V provides better adaptability to industrial environments , and the DIN rail mounting accessories that can be equipped are suitable for DIN rail installation.

3 Implementation Standards

"Q/GDW 1365-2013 Technical Specification for Security Certification of Smart Electricity Meter Information Exchange" State Grid Standard

"Three-phase smart energy meter type specification Q/GDW1356-2013" State Grid Standard

4 Technical Parameters

4.1 Appearance 

Interface: 485: Terminal block; 422: Terminal block

Power supply: positive inside and negative outside, standard power socket; two-wire terminal

Size: L x W x H = 9.4cm x 6.5cm x 2.5cm

Panel lights: 1. ACT: When the ACT light is green, it means that data is being transmitted normally between Ethernet and RS485. When the ACT light flashes blue, it means that data is being returned from RS485 to Ethernet. If the data is short, the blue flashing time is short, so you need to pay attention.

2. LINK: When the LINK light is green, it means the RJ45 network cable is connected. When the LINK light is blue, it means the TCP connection is established or in UDP mode.

3. POWER: Indicates that the serial port server is powered on.
