  • 驱动器数量:2 路驱动,支持双通道差分传输
  • 支持节点:最多 256 个节点,适配大规模分布式系统
  • 静态电流:30 mA(典型),优化能耗
  • 静电保护:±15 kV,提高现场静电防护能力
  • 功能特性:内置失效保护电路与总线故障检测,支持快速故障定位与隔离
  • 集成隔离电源:简化外部电源设计,提升系统集成度
  • 逻辑侧工作电压:3.15 V ~ 3.45 V,兼容主流 3.3 V MCU/FPGA
  • 工作温度:-40°C ~ +85°C,适应严苛环境
  • 封装:插件,尺寸 19.5 × 16.5 mm,便于替换与调试

三、典型应用场景

  • 工业现场总线与有线实时通信(如工业以太网扩展、运动控制总线)
  • 分布式传感与执行器网络(多节点数据采集与控制)
  • 电力及能源管理系统中的隔离通信接口
  • 电机控制与驱动器之间的高速差分链路
  • 严苛电磁环境下需要高共模抗扰的通信系统

四、技术规格摘要

  • 最大数据速率:10 Mbps(全双工)
  • 隔离电压(Vrms):2500
  • CMTI:15 kV/μs
  • 驱动器数:2
  • 静态电流:30 mA
  • 支持节点数:256
  • 静电保护:±15 kV
  • 逻辑侧工作电压:3.15 V ~ 3.45 V
  • 工作温度:-40°C ~ +85°C
  • 封装:插件,19.5 × 16.5 mm

五、使用建议与注意事项

  • 布线:差分对需保持恒定阻抗并避免长距离不对称走线,以保证高速传输完整性。
  • 接地:模块提供隔离,外部系统须根据安全等级对接地和屏蔽进行合理设计,防止共模干扰耦入。
  • 散热:尽管静态电流低,若在高环境温度或高密度集成时需评估散热路径,保证可靠运行。
  • 故障管理:利用模块的总线故障检测与失效保护电路,可在系统级实现快速隔离与报警策略,建议在上位控制器中加入相应的异常处理逻辑。
  • EMC 设计:模块具备高 CMTI,但系统级 EMC 仍需注意滤波、TVS 和布局,尤其是在电机驱动与逆变器等强干扰场合。

六、包装与可靠性

RSM3422P 采用插件式封装,尺寸 19.5 × 16.5 mm,便于现场插拔和维修。器件在工业温度范围内通过长期老化验证,适合需要长期稳定工作的工业控制与通信场合。有关认证、详细引脚定义与参考设计,可联系 YLPTEC(易川)获取器件数据手册与应用笔记。

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
