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 ...

This multi-channel analog output module TI Design with multiplexed single channel digital to analog converter (DAC) for programmable logic controllers (PLC) illustrates the design of low-cost, ...

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 ...

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 ...

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 ...

See what end users and system integrators prioritize in their I/O technology choices, such as specific Ethernet connectivity, multiple protocol handling, and high density/smaller footprint. Learn ...

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 ...
