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鈩?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.
