ALE111-S00
光ESB总线中继器模块由ESB总线转换而成，连接安全控制单元、安全节点之间
单元和N-IO节点，到光信号。
通过连接光ESB总线中继器主模块，可以延长ESB总线的传输距离
(SNT401)和光ESB总线中继从站模块(SNT501)，带一根光缆。
通过连接光ESB，可以将ESB总线的传输距离扩展到5km以内
总线中继器主模块(SNT401)在主端到N-ESB总线模块(S2EN501)在从端和N-ESB
主端总线模块(S2EN501)到从端光ESB总线中继器从端模块(SNT501)
光纤电缆。
l snt401光ESB总线中继器主模块
该模块从安全控制单元或ESB总线上的ESB总线耦合器模块(SEC401, SEC402)连接
安全节点单元(SNB10D)上的SSB401接口模块(SSB401)通过ESB Bus线缆连接。
有两种类型的ESB总线中继器模块:带终止器或不带终止器。
l snt501光ESB总线中继器从站模块
该模块由光ESB总线中继器主模块或N-ESB总线模块通过光纤连接
电缆。通过ESB总线线缆连接到安全节点上的ESB总线接口模块(SSB401)
单位(SNB10D)。
