Your first step is to verify that the module is the correct one for this control loop — unless this specific module has worked correctly before. Whether it has or not, you need to use a meter to test ...

New AC and DC discrete I/O modules include 8-point, 100-120 VAC input and output modules, 8- and 15-point, 3.3-24 VDC input and output modules and high-density, 32-point,12-24 VDC input modules. The I ...

Analog CPU modules released for small PLC line. Variety of analog and discrete I/O enhance versatility in small form factor. The Click PLC from AutomationDirect now includes three analog CPU models.

The isolated analog input module presented here is particularly suitable for industrial electronics applications ... from the field. My solution is a voltage-to-frequency (V-F) converter circuit with ...

The MAXREFDES177# design includes a MAX22000 industrial universal analog I/O device that’s fully software-configurable for all common industrial analog input/output, voltage, and current ranges.

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 ...

The mapping between plc points and physical I/O is left to the configuration of the I/O modules. Therefore, it is possible to have the same plc point mapped to more than one output. The opposite is ...

Does the module's output correspond correctly to its input? Determine that by forcing the PLC output to 10%, 25%, 50%, 75%, and 90% and measuring on the output terminals at the corresponding range.
