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 ...

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 ...

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 ...

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 ...

The DRSL-U accepts a wide range of inputs, including RTD, thermocouple, potentiometer, linear resistance, current or voltage input and converts these signals to linear current or voltage output. The ...

AUSTIN, Texas--(BUSINESS WIRE)--Silicon Labs (NASDAQ: SLAB) has introduced the industry’s first high-speed, multi-channel digital isolators designed to meet the demands of programmable logic ...

Analog Devices, Inc. (ADI) introduced today two multi-channel +/-10V and 0-20mA precision A/D converters that better enable implementation of programmable logic controller (PLC) and distributed ...

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 ...

Narrow-band low-frequency power-line communications (NB LF PLC) is a hot topic these days. Engineers creating PLC modems must consider which PLC standard (PRIME, G3, S-FSK) will be used and which ...
