I/O modules are building blocks of industrial control systems used in end equipment such as PLC (Programmable Logic Controllers), PAC (Programmable Automation Controller) and DCS (Distributed Control ...
Two analog-output modules, the BusWorks 972EN and 973EN, convert Ethernet Modbus/TCP instructions from network controllers to DC voltage or current outputs for driving as many as six measurement or ...
In our previous two issues, we discussed troubleshooting digital output modules. Troubleshooting analog modules is a bit more complicated, for two reasons: Analog modules aren't on/off, as digital ...
AutomationDirect’s Productivity2000 programmable controller line now includes 12 and 13-bit resolution current and voltage analog input and output modules for cost-conscious applications.
Acromag expands their line of BusWorksXT Ethernet I/O modules that are ideal for remote monitoring, distributed control, or SCADA applications. Models are offered in Ethernet communication protocols ...
Schweitzer Engineering Laboratories, Inc. has announced new modules and protocols for its remote terminal unit or programmable logic control platform, the SEL-2240 Axion. Customers can now order ...
In the broad-brush view of the analog-to-digital converter (ADC) versus its complement, the digital-to-analog converter (DAC), there’s no doubt that the DAC has an easier functional challenge. What’s ...
Does the module's output correspond correctly to its input? Determine that by forcing the PLC output to 10%, 25%, 50%, 75%, and 90% and measuring on the output terminals at the corresponding range ...
