TD501D485H 半双工RS485收发器产品概述

一、产品定位与核心功能

TD501D485H是YLPTEC(易川)推出的工业级半双工RS485收发器,核心作用是实现RS485总线与微控制器(MCU)之间的双向数据转换,支持点对多组网通信。产品专为中低速、多节点的工业通信场景设计,可替代进口同类器件,是工业自动化、楼宇自控等领域的高性价比接口解决方案。

二、核心技术参数与优势

(一)稳定的数据传输性能

产品支持最高115.2Kbps的数据传输速率,满足工业现场常见的传感器数据采集、设备状态监控等中低速通信需求;传输过程中信号完整性良好,误码率低,适合对数据可靠性要求较高的场景。

(二)强化的电气防护与隔离

  • 内置静电保护(ESD) 功能,可有效抵御现场静电干扰(如人体接触、设备插拔产生的静电),提升设备抗冲击能力;
  • 具备2500Vrms(有效值)电气隔离,能阻断总线与本地电路之间的地环流,避免共模干扰导致的通信异常,适配工业现场复杂的接地环境(如不同设备接地电位差较大的场景)。

(三)宽范围电源与低功耗设计

  • 工作电压覆盖4.75V~5.25V,兼容主流5V电源系统(如MCU供电、开关电源输出),无需额外电压转换电路,简化系统设计;
  • 静态电流仅28mA,在待机或低负载状态下功耗可控,适合对功耗敏感的嵌入式系统(如电池供电的远程采集终端)。

(四)多节点组网支持

产品支持最大64个通信节点,可满足工业现场多设备(如传感器、PLC、HMI)的总线式组网需求,无需额外扩展芯片即可实现“一主多从”通信;虽不支持自动流控,但在中低速、节点数可控的场景下,通过手动流控或轮询机制仍可稳定运行。

(五)宽温工作环境

工作温度范围为**-40℃~+85℃**,完全覆盖工业级环境要求,可在户外低温(如北方冬季室外)、车间高温(如冶金车间)等极端场景下长期稳定工作,无需额外散热或保温措施。

三、典型应用场景

TD501D485H的特性使其适用于以下场景:

  1. 工业自动化:PLC与温度传感器、压力变送器、执行器的通信组网;
  2. 楼宇自控系统:空调机组、照明控制器、门禁系统的总线式数据交互;
  3. 安防监控:网络摄像头、门禁读卡器与管理主机的RS485总线通信;
  4. 智能交通:交通信号灯控制器、卡口测速设备的数据采集与控制;
  5. 电力监控:智能电表、配电终端与集中器的远程抄表通信。

四、封装与引脚特性

产品采用DIP-8直插式封装,引脚布局符合常规RS485收发器标准,便于手工焊接、原型开发及批量生产中的插件组装。典型引脚功能(参考工业级RS485通用定义)包括:

  • VCC(电源正)、GND(电源地);
  • DI(数据输入,MCU输出→总线)、RO(数据输出,总线→MCU输入);
  • DE(发送使能)、RE(接收使能,可通过MCU引脚控制收发切换);
  • A(总线正)、B(总线负)。

引脚兼容性强,可直接替换同类工业级RS485收发器,降低系统升级成本。

五、品牌与可靠性保障

YLPTEC(易川)作为专业电子元器件厂商,TD501D485H经过严格的工业级可靠性测试(包括高低温循环、电气隔离耐压、静电放电、振动冲击等),确保在复杂工业环境下的长期稳定运行,是替代进口同类产品的高性价比选择。

总结:TD501D485H凭借宽温工作、高隔离防护、多节点支持等特性,成为工业通信领域RS485接口的理想解决方案,适用于对成本敏感且需稳定通信的各类应用场景。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
