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 ...

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 ...

The MAXREFDES67# reference design is a complete universal analog input for industrial applications. This unique 24-bit front-end accepts bipolar voltage and current, resistance temperature detector ...

The new CPUs feature two analog inputs and two outputs with ranges of voltage up to 5 VDC or current up to 20 mA. The modules include two built-in RS-232 and one RS-485 communication ports, and real ...

Electronic engineers, developers and hobbyists looking for a fully featured Arduino Mega compatible PLC may be interested in a new Indiegogo campaign launched today for a new development board ...

The new CPUs feature two analog inputs and two outputs with ranges of voltage up to 5VDC or current up to 20mA. The modules include two built-in RS-232 communication ports and one RS-485 port, as well ...
