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 ...

By definition, digital inputs are either on or off. Thus, verifying the absence or presence of voltage is a critical part of troubleshooting digital input modules ...

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 ...

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.

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.

Model NT2140 discrete AC power input modules have joined the BusWorks NT2000 Ethernet remote I/O family, and can sense on/off ...

Three new 32-point discrete I/O and five analog I/O expansion modules as well as three new temperature input modules have been added. Three 4-channel analog input and two 4-channel analog output ...

Designed by Namnam in Vietnam, the ESP32 Modbus gateway is built to communicate with PLCs and industrial sensors over Modbus ...
