Safety Evaluation with TIA Selection Tool Much more than just an evaluation of safety functions Configure and order your I/O systems with the TIA Selection Tool and use the same tool for your safety evaluation. Safety Evaluation with TIA Selection Tool makes it even faster and ...
故障安全模块的设计目的是在检测到故障时，能够迅速将系统引导至安全状态。这类模块在分布式控制系统中尤为常见。与普通模块不同，故障安全模块内部采用了双通道设计，两个处理器相互监控并自动检测IO回路的状态，从而在故障发生时能够立即将模块置于安全状态。在西门子S7系列PLC中，故障安全模块的种类繁多，包括电源模块、...
Fail-Safe I/O to Achieve Ultra Low System PowerThe disclosure provides an input/output (IO) circuit powered by an input/output (IO) supply voltage. The IO circuit includes a cutoff circuit that receives a first invert signal, the IO supply voltage, a bias voltage and a pad voltage. An ...
