General Description
The Field Tools 24V Supply provides portable power to loop powered devices.
It is a fully contained power source that takes the low voltage from three “AAA”
alkaline batteries and increases it to a highly
fi
ltered 24 volts DC. Using batteries
for the power source eliminates isolation concerns as well as the need for a
power connection to AC or a USB port. The voltage conversion is done using
a high ef
fi
ciency switching DC-DC converter to maximize battery life. Simply
connect the two mini-clips to the power input of your loop powered device.
A push-button is used to enable or disable the 24 volts while a status LED
indicates the active operating mode. An internal 250 ohm loop resistor, HART
protocol modem clip points, and current meter leads with standard banana jacks
make the 24V Supply a complete loop transmitter power solution.
