AutomationDirect's acuAMP line of current sensors now
includes ac ground fault sensors and dc current transducers and switches. The
GFS series monitors current-carrying conductors in grounded single and
three-phase delta or wye systems. Available in fixed-core models, the GFS
series features jumper-selectable setpoints of 5, 10 or 30 mA. The sensors can
accommodate up to 14 AWG copper wire and feature mechanical relay outputs with
either manual or auto reset. The sensors are UL and CE approved.
The DCT series of dc current transducers combine a Hall Effect sensor and
signal conditioner for use in dc current applications up to 400A. Designed to
be compatible with most PLCs, data loggers and SCADA systems, the DCT series
features jumper-selectable current input ranges and 4-20 mA or +/- 10V dc
outputs. Available in split-core or fixed-core models, DCT current transducer
prices start at $117.
DCS100 series dc current switches feature jumper-selectable current input
ranges up to 100A and are available in normally-open solid-state and SPDT relay
output models. The switches are equipped with removable terminal blocks which
accept up to 12 AWG solid or stranded wire.
All acuAMP sensors are panel-mountable; convenient DIN rail adaptor
accessories are also available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
