XTR501

The XTR501 contains a high efficiency DC/DC converter and 4-20mA three wire current transmitter. XTR501 provides regulated bridge excitation, optional half bridge, differential inputs and current transmitter necessary for the excitation and signal conditioning of low impedance bridge sensors and high integrity signal transmission.

The XTR501 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 100W when exciting low impedance sensors.

The instrumentation amplifier of the current transmitter can be used over a wide range of gains, accommodating   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 leading to considerable savings on cabling costs.
