Higher amperage relay output modules and an 8-point input simulator module are now available from AutomationDirect for the Click series stackable micro brick PLCs. The Click C0-04TRS-10 ($54.00) is a ...

The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

In previous issues, we have discussed troubleshooting input modules. In the examples, the output modules checked out OK. But what if they don't? As with input modules, output modules can be digital or ...

Two new eight-channel, configurable Digital Input/Output (DIO) Modules have joined WAGO Corporation's IP67 SPEEDWAY 767 I/O-SYSTEM. Configurable channel-by-channel, the 767-5801 & 767-5802 modules ...

PLC Inputs and Outputs provides an overview of the main types of input/output modules and input/output devices, their primary functions, and their roles in a PLC process. In a PLC system, the ...

It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

In my previous article on photovoltaic (PV) systems (“The Highs and Lows of Photovoltaic System Calculations” in the July 2012 issue), I went through methods to calculate the changes in voltage due to ...

Paralleling of MicroVerter® DC/DC converters is often used to increase the output power capability of a single unit by connecting the outputs of two or more converters in parallel. By connecting the ...

Flex Power Modules has announced the BMR490 DC-DC converter with active current sharing. This feature enables two or more converters to be used in parallel for demanding datacom applications, thus ...

Point of Load (PoL) dc-dc converter modules provide regulated dc power to a wide variety of loads. PoLs are small, efficient and relatively inexpensive, so their ability to provide common powering ...
