Ansaldo STS USA Monday announced its VitalNet™ Current Sensor for use in Positive Train Control applications, as mandated for most Class I rail rights-of-way by the Rail Safety Improvement Act of 2008. The company says the VitalNet Current sensor reduces the labor and improves quality and safety.


Ansaldo STS USA will display the new product at the RSSI C&S Exhibition in Omaha, Neb., May 18 and 19, and will formally present the productin the RSSI Innovation Theater at 5:00 p.m. Tuesday, the 18th.

The current sensor combines the best current-sensing technologyavailable into one device: a small, light package, diversity in detection and closedloop control capability. The form factor allows for installation without disarrangement, providing simple PTC installation on lamp signals, the company says.

The VitalNet Current Sensor is a prewired solution thatfeatures upper and lower current sensing tabs—in between are two currentmeasuring elements. Each element is able to make individual measurements that the controller can compare for diversity. In combination with voltage detection, the current sensor allows for full vital signal detection for both AC and DC currents.

Other new Ansaldo STS USA products that will be featured atRSSI include: the VitalNet Point Monitor—hand throw switch monitoring for PTC; the VitalNet WIU, a  stand-alone wayside interface unit; MicroLok® II VitalNet CPU, a wayside interface unit upgrade for PTC in existing interlocking locations; and RailSentry™, a security product.
