milliamperes for driving relays or lamps. ADM1270 provides inrush
current limiting and overcurrent protection for such inductive or
resistive loads. A typical application example can be found on the
evaluation board of the AD74413R.
When HART modulation is required, an AD5700 can provide modem
functionality for AD74413R-based systems.
Because the scope of this review encompassed industrial
applications, we mainly discussed the AD74413R. A lighter version,
called AD74412R, is targeted at building control applications. It has
a reduced operating temperature range of -40°C to +85°C, more
relaxed current input and output accuracies, and supply voltages
up to 26.4V.
Conclusion
With the right SWIO ICs, manufacturers can develop a platform
that replaces multiple aging fixed-function I/O modules. Moreover,
they can use this technology across multiple end applications
where the I/O dynamically changes with each installation. For
systems traditionally reliant on control cabinets with multiple I/O
modules and specified wiring for each channel type, the need for
hardware disappears as end users can now install a single module
programmable from the control room, helping to decrease product
management, logistic, manufacturing, and support costs. SWIO
technology also acts as a bridge to Ethernet-based control networks
since it can be applied to already available installations.
