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, ...
In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...
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 D0-DCM and the F0-CP128 are new communications modules for the DL05/DL06 micro PLC family. The D0-DCM module adds two serial ports to any DL05 or DL06 PLC, using RS-232 or RS422/485 data ...
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 ...
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 ...
This file type includes high-resolution graphics and schematics when applicable. One of the key parts of automation is observing variation, and a process’ ability to control it. Reducing variation ...
