PLC 可编程功能具有较高的灵活性可满足多种应用

25 个开关量输入和 18 个出口继电器

灵活连接满足所有通信需求

工作原理：

RET543AM240AAAA 在正常运行状态下，馈线终端会实时监测馈电线路的运行参数，并通过CAN总线向配电子站发送这些参数。

馈线终端也可以工作在监控状态下，定时向配电子站发送相关参数。

当接收到配电子站的命令时，馈线终端会执行相应的操作，如线路开关的合闸和分闸。

特性与要求：

RET543AM240AAAA馈线终端需要能够适应较恶劣的运行环境，能够在-30℃至+60℃的温度变化范围内正常工作，并具有良好的防潮、防雨、防腐蚀措施。

由于馈线终端通常安装在电力线柱上或组合式配电柜内，因此要求其体积小、便于安装，并且功耗要尽量小。

馈线终端还需要具备很高的抗干扰能力，能够承受高电压、大电流、雷电等干扰。

应用场景：

馈线终端主要应用于电力系统中的架空配电线路和电缆线路环网柜的监控。

它通过实时监测和上报馈电线路的运行参数，以及执行配电子站的命令，实现对配电网的优化管理和故障处理。

Depth 102 mm (4.01 "), 111 mm (4.37 ") including connector

Height 119 mm (4.7 in)

Weight 0.21 kg (0.46 lb)

Used to protect, control, measure and monitor medium voltage power grids

The REF 543 feeder terminal can be used in combination with a variety of switching devices, including single-bus, dual-bus and dual-machine systems.

The RET543AM240AAAA protection function also supports various types of networks, such as neutral ungrounded networks, arc suppression coil grounded networks, and partially grounded networks. Its application scope also covers the protection and control of medium-sized three-phase asynchronous motors and reactive power compensation shunt capacitor banks. In addition to protection, measurement, control, condition monitoring and general functions, the REF 543 feeder terminal provides a large number of PLC functions, which allows the multiple automation and sequential logic control functions required for substation automation to be integrated in a single unit.

Data communication supports the following communication standards: SPA bus protocol, LON bus protocol, IEC 60870-5-103 protocol, IEC 61850 supported by SPA-ZC 400, Profitbus DPV1 protocol supported by SPA-ZC 302, DNP 3.0 and Modbus for upper devices Communication protocol. In addition, the LON communication protocol combined with PLC functionality reduces the need for hard wiring between feeder terminals.

Major advantage

A large selection of protection features

PLC programmable features provide high flexibility to meet a wide range of applications

25 switching inputs and 18 outlet relays

Flexible connectivity for all communication needs

How it works:

RET543AM240AAAA Under normal operation, the feeder terminal will monitor the operating parameters of the feed line in real time and send these parameters to the distribution station through the CAN bus.

The feeder terminal can also work in the monitoring state and periodically send relevant parameters to the distribution station.

When receiving the command of the distribution station, the feeder terminal will perform the corresponding operations, such as the closing and opening of the line switch.

Features and requirements:

The RET543AM240AAAA feeder terminal should be able to adapt to the harsher operating environment, be able to work normally in the temperature range of -30 ° C to +60 ° C, and have good moisture, rain and corrosion protection measures.

Because the feeder terminal is usually installed on the power line post or in the combined distribution cabinet, it is required to be small in size, easy to install, and power consumption should be as small as possible.

The feeder terminal also needs to have a high anti-interference ability to withstand high voltage, high current, lightning and other interference.

Application scenario:

Feeder terminals are mainly used in the monitoring of overhead distribution lines and cable circuit cabinets in power systems.

By monitoring and reporting the running parameters of the feed line in real time, and executing the command of the distribution station, it realizes the optimal management and fault handling of the distribution network.
