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 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 trend towards increased monitoring in industrial automation and process control requires input modules with higher channel densities. In these applications, 24V DC digital inputs (DI) make up the ...

Independent of their individual topology and application, due to AC components in their lines switching controllers create conducted EMC interferences. Würth Elektronik MagI³C power modules are ...

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 ...

Two new modules for the vendor’s PACSystems RX3i system are said to reduce downtime, provide high resolution for improved process control and high-performance sampling of data to improve throughput.
