In our previous issue, we noted that the first step in troubleshooting digital input modules is to verify the power source of each loop. If input power is missing, the causes can be such things as ...

The isolated analog input module presented here is particularly suitable for industrial electronics applications. Sending analog signals from field sensors over long-distance cables is often difficult ...

Industrial digital input chips provide serialized data by default. However, in systems that require real time, low latency, or higher speed, it may be preferable to provide level-translated, real-time ...

The following are some basic facts about input loop power sources: The input module usually isn't a loop power source. Although 120V is common for digital loops, other voltages are also used. There ...

Touted as the world’s first TUV SIL 3 certified Hart failsafe analog input module, the Simatic SM 336 is available for use with Simatic ET 200M I/O and PCS 7F process safety systems. July 1, 2008 A 50 ...
