5 structural characteristics

The device adopts a rear plug-in structure with a closed shell; The chassis adopts embedded installation method and is wired behind the box.

Dimensions of the device: 223 × 262 × 240mm (height × width × depth);

Installation hole size: 223 × 227mm (height × width);

Installation fixed hole spacing: 140 × 246mm (height × width), installation hole: 4 × Φ 8mm.

The device design adopts a modular design concept, where different configuration requirements are combined and configured by various functional components as needed, achieving standardization of functional modules. The device consists of an analog input AI plugin, a main control MAIN plugin, a basic remote signaling DI plugin, a power/output POW plugin, a communication TX plugin, and a human-machine interface MMI component on the panel.

From right to left on the back of the chassis (as shown in Figure 3.2-1), they are: analog input AI plugin (A), main control MAIN plugin (B), basic remote signaling DI plugin (C), extended remote signaling DI plugin (D), power/output POW plugin (E), and communication TX plugin (F). The standard configuration of the device includes (A), (B), (C), (E), and (F), with 5 plugins that can meet the needs of telemetry and remote signal acquisition, output control, communication management, and ring network. If users need to add special switch signal acquisition, they can expand it by extending the remote signal DI plugin (D).

Figure 3.2-1

5.1.1 Analog inputAIPlugin(A)

The AI plugin for analog input comes standard with 6-channel current and 6-channel voltage acquisition, which can collect analog signals such as three-phase AC current and three-phase AC voltage. After the AC current and AC voltage are isolated and converted into small signals through internal transformers, they are sent to the main control MAIN plugin for signal conditioning and analog signal acquisition and calculation.

5.1.2 Main control plugin(B)

The main control MAIN plugin is the core plugin of this device, which includes analog signal conditioning, acquisition, AD conversion, protection discrimination, switch quantity acquisition, parameter and historical record storage, Real-time hard clock, etc.

The internal main control MAIN plugin and communication TX plugin of the device are directly interconnected through an internal serial port for data exchange and command execution.

5.1.3 teleindicationDI plugin（C)

The device comes standard with one basic remote signaling plugin (C). When the basic remote signaling plugin cannot meet the configuration requirements, the input capacity can be expanded by extending the remote signaling plugin (D). The basic remote signaling plugin and the extended remote signaling plugin have the same Hardware, which needs to be selected through the JP1 jumper on the remote signaling plugin. Short circuit of pins 1-2 of JP1 jumper: for basic remote signaling plug-in (C); Short circuit of pins 2-3 of JP1 jumper: for expanding the remote signaling plug-in (D).

5.1.4 Power supply/POW plug-in（E)

The power/output plug-in adopts a wide input range AC/DC dual-purpose switch power supply, with AC/DC85-265V input and DC5V output, for use in digital and analog circuits of the device.

The opening section provides 8 open contacts to achieve remote control tripping/closing control of switches, protection tripping control, and other outputs.

The power/output plug-in can be optionally equipped with a 1-way operation box, which needs to be specified by the user when ordering.

5.1.5 Communication TXPlugin(F)

The communication TX plugin is configured with communication management machine function and ring network switch function.

The communication management machine is equipped with RS485 serial port and RJ45 network port, which can receive and forward multiple protocols Protocol in the power system.

The communication TX plugin also embeds a ring network switch, which can achieve fiber self-healing ring network. The ring network switch is configured with 2 electrical ports and 2 optical ports, supporting multiple devices to network through the network.

Special note: In order to simplify the external network cable when connecting the communication management machine to the ring network switch, there is a network interface directly connected between the communication management machine and the ring network switch inside the device. When the communication management machine does not need to be directly connected to the ring network switch, all four hop blocks at JP1 position on the communication TX plugin need to be opened to avoid device IP address conflicts and affect network communication.

The default IP address for the communication TX plugin network port is as follows:

(1) The default IP address for NET1 is 192.168.1.166.

(2) The default IP address for NET2 is 192.168.3.166.

(3) The default IP address for the network port directly connected to the internal management machine and switch of the device is 192.168.2.166.
