过电压保护装置/手动操作模块
型号型号 789-811
789-810 数字手动操作模块监测 0...3 路输入，并通过绿色 LED 指示它们的状态，同时为继电器的转换接点提供电源。根据手动/自动开关和监控输入，会将状态 0 或 1（电气隔离）通过继电器传输到输出。
789-811 模拟手动操作模块监测 0...3 路模拟输入。根据手动/自动开关和监控输入，会向输出传输 0 到 10V 设定电压。
过电压保护装置/信号技术用浪涌抑制模块
型号型号 792-804
Short description:
Provides surge protection for IT systems and devices in the voltage range up to 60 V (except custom solutions, e.g., telephone systems with ringing voltage).
Overvoltage protection is also possible for DIN-35 rail-mount terminal blocks. Multi-stage surge arresters in rail-mount terminal blocks (792-80x Series) of just 6 mm width ensure cost-effective protection for control and bus technology (e.g., LON® network, PROFIBUS network, binary signals).
Features:
- Protect your system against overvoltage
- Slim, space-saving design
- Control operational costs by preventing expensive, unplanned downtime
- High operational reliability and system uptime
