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 ...

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 ...

A key subsystem in a programmable logic controller is the analog input module, which provides a high-precision front end to measure a wide variety of sensors. In many cases, however, the amplifier ...

Cells are often reprogrammed to alter their output and churn out desirable products. And, increasingly, they are being reprogrammed to sense external cues, and thereby accept new input. But imagine ...

Safety-relevant output modules as well as a logic module with expanded functional scope have been added to modules already available. Fourteen different safety-relevant function modules, from a simple ...

The BusWorks 965EN Input Modules interface thermocouple and millivolt signals directly to an Ethernet Modbus/TCP 10/100 network. The six-channel, inch-wide I/O modules operate independently of any bus ...

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 ...
