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 ...

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 ...

The trend of Industry 4.0 marks a move of factory systems away from large, centralized programmable logic controllers (PLCs) toward modular, decentralized Micro PLCs that promise to provide better ...

AutomationDirect's Productivity2000 programmable logic controller provides two independent single-ended 5-24 VDC inputs that accept up to 100kHz of pulse/direction and quadrature signals. The ...

Maxim Integrated Products has released a reference design to generate analog output from industrial programmable logic controllers. The reference design called Alameda has four high-accuracy ( ±0.1%) ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...

Allegro MicroSystems, Inc. introduces a new dual analog/PWM output, one-time programmable, linear IC which allows the user to optimize the device in a finished sensor assembly. Allegro MicroSystems, ...

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 ...
