  AD-KAB 40 GT和AD-KAB 80 GT

产品介绍 使用RS485继电器模块AD-KAB 40 GT和AD-KAB 80 GT,可以通过RS485总线远程控制4个或8个无电位的常开触点。在RS485总线上使用的Modbus-RTU协议是一种开放标准,因此非常灵活。最多可以通过单独的Modbus寄存器对八个继电器进行个别控制。这些设备配备有两个旋转编码开关,可用于在设备上设置总线地址。如果DIP开关处于活动状态(手动操作中),则会忽略相应继电器的总线命令,因为手动操作具有优先权。由于紧凑而高效的开关电源,这些设备可以在广泛的供电电压范围内运行。 产品参数

  AD-VARIOCONTROL, AD-VARIOCONNECT

产品介绍 可拆卸的控制模块AD-VarioControl用于显示具有相关接口的基础设备(发射器、隔离放大器等...)的测量值。插入后(即使在基础设备运行期间也可以无限制地插入),基础设备将被自动读取,并显示相应的测量值。除了显示功能外,还可以访问基础设备的参数和控制功能。可以使用备份功能将参数设置加载到控制面板中,并在相同类型的不同基础设备上进行恢复。 建立发射器通常只需要在设备的操作周期内进行一次,因此并非每个设备都需要永久性的显示和操作元素。通过将AD-VarioControl与兼容的基础设备配合使用,可以省去每个单独设备上的操作元素和显示。这样,安装的设备就是防篡改的,并且更具成本效益。 AD-VarioConnect具有通过RS485的Modbus-RTU协议的现场总线接口。通过这个接口,可以获取基本单元的所有测量值。 产品参数
