DESCRIPTION
The XTR501 contains a high efficiency DC/DC con-
verter and 4-20mA three wire current transmitter. It
provides regulated bridge excitation, optional half
bridge, differential inputs and current transmitter nec-
essary for the excitation and signal conditioning of
low impedance bridge sensors and high integrity sig-
nal transmission.
The DC/DC converter is capable of supplying 1W into
a regulated bridge voltage of 1.5V to 5.0V from a
supply of 11.4V to 30V. The combination of a low
startup current and high efficiency current step-up
allows for a combined supply line resistance of up to
100
when exciting low impedance sensors.
The instrumentation amplifier of the current transmit-
ter can be used over a wide range of gains, accommo-
dating a variety of input signals and sensors.
The XTR501 is particularly suited to excitation of
high current/low impedance sensors used in bridge
applications allowing the use of lighter cabling lead-
ing to considerable savings on cabling costs.
