上海积进自动化设备有限公司：专业经营德国菲尼克斯（PHOENIX）电气产品：菲尼克斯开关电源，菲尼克斯隔离器，
菲尼克斯变送器，菲尼克斯交换机，菲尼克斯继电器，菲尼克斯安全继电器，菲尼克斯模块，菲尼克斯转换器，菲尼克斯端子，
菲尼克斯防雷器，。。。。。。菲尼克斯PLC-R系列继电器
PLC-R…21 是通用型继电器接口系列产品，它由底座接线端子和带转换触点的可插拔微型继电器组成。功能化可插拔式桥接件将显著减轻接线工作量，同时把错接可能性降到Z低限度。这些模块有螺钉连接和回拉式弹簧连接形式，当然它们拥有统一的外形。通用型转换触点系列产品PLC-R…21 将总是用在那些灵活性要求高的场合。例如它可以
– 作为输入或者输出接口
– 起常闭、常开或者转换触点的作用，并将显著降低仓库管理费用。
常规供货时， PLC 接口装有继电器或者微型光电耦合器。当然也可以满足用户的特殊组合要求。
在PLC 和执行器( 例如电动机、接触器8或电磁阀) 之间的接口应用中，通常只需要一个常开触点功能。菲尼克斯为此提供PLCACT执行器型输出接口，该接口由带螺钉或弹簧连接方式的6.2mm基座和可插拔式小型继电器或光耦组成。
菲尼克斯继电器用于高接通电流负载（照明灯、容性负载等）PLC 接口是超薄、可插拔和灵巧的模块式接口，它带有使用方便的插拔式桥接系统。该系列现在新增了特型继电器接口产品，用于特殊的负载场合，如照明灯负载、容性负载或持续大电流的负载。
