Here’s the reference schematic of the digital power supply module. As explained in the first installment of this serial article, dc output voltage and current levels are constantly monitored (and ...

In our previous issue, we said a digital output module could be tested by using the PLC logic to force the output on and off then and observing the module’s response. If the module doesn't respond, ...

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 ...

The Expert I/O 1000 input/output control module features a simple USB connection to control 16 digital inputs, 16 digital outputs, two analog outputs, six analog inputs, and two brush dc motor ...

Designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function ...

To meet safety requirements, positively driven feedback contacts must be evaluated in a manner that is appropriate for safety technology. This module evaluates this data internally, making it just as ...

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 ...
