Check the module's power and logic indicators. They should change state as you vary that input. If they don't, the module isn't responding. This used to mean an automatic replacement, but it may be ...

In this design the industrial digital-input serializer (U1) translates, conditions, and serializes the 24V digital output of sensors and switches to CMOS-compatible signals required by ...

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 ...

MRS Electronic, a provider of smart and electronic solutions for the automotive industry, has added compact, networked ...

Higher amperage relay output modules and an 8-point input simulator module are now available from AutomationDirect for the Click series stackable micro brick PLCs. The Click C0-04TRS-10 ($54.00) is a ...

High speed, multi-channel digital isolators from Silicon Labs, are suited to programmable logic controller (PLC) applications, including industrial I/O modules, CNC machines and servo motor control.

Digital input serializers (DIS), the heart of digital input modules, must operate in harsh industrial environments. Voltage and current transients caused by electrostatic discharge, switching of ...

“he new CANADUINO MEGA 2560 PLC 500 is based on an Arduino MEGA 2560 compatible computing module and comes in two versions for 100-240V AC line power (model 500 AC) or 12-24V DC power supply ...
