Model 500 Jumper Keeper Alarm System
The Model 500 Jumper Keeper (US Patent No. 5,917,419) will help a conscientious signalman limit the risk of left-jumpers. Jumper Keeper is inserted into the standard routine of jumper use, requiring no extra effort on the part of the maintainer to achieve the improvements in safety. Responsibility for jumpers is kept where it belongs; with the individual using them. Dash and Rack Unit Set accommodates 6 jumpers. Visual and audible alarms respond when vehicle ignition is on and a jumper is missing. 10 minute time-out is push-button activated and is repeatable. Where more than 6 jumpers are required Extension Rack Units can be used to add jumpers in multiples of 6, up to a total of 30 jumpers. Numbered jumpers with company identification are also available.

S&C Distribution Company is pleased to offer two data recorders that address the needs of railroad signalmen. Our Portable Digital Data Recorders (PDDR's) provide the means to monitor up to eight contact closures and/or floating outputs such as those provided by GCP's (r) or VHLC's (r), and time/date stamp their activity. The PDDR is in a package that is designed to be moved from location to location. Two units feature either a recording format that will not auto-erase until downloaded, insuring that intermittent problem events are not lost if it is inconvenient for the installer to return to the site within the memory consumption time, or one with switch-selectable auto-erase and no auto-erase (Protective) modes enabling the user to choose his recording format. Can be ordered with either a DB-9 or a USB comm. port.

Memory capacity is rated in events and/or days (16). A real-time clock/calendar date and time stamps each sampling. The memory element itself is four rewriteable, nonvolatile EEPROMs. To insure complete isolation of the equipment under measurement, the I/O employ opto-coupler interfaces. All 8 I/O Ports are provided with isolated commons.

While a computer is necessary to take full advantage of deign refinements of the PDDR, properly time-stamped data collection can begin within one minute of hook-up. Fast-Track set-up utilizes pushbuttons on the PDDR, eliminating the need for a computer altogether.

The PDDR can be powered by any of three alternatives; local battery, 120VAC (power supply provided with the unit) and an optional, plug-in, rechargeable battery pack. Current usage is 80 mA at 5 VDC (internally regulated).

SYSTEM REQUIREMENTS

A computer is used during setup of the PDDR and for retrieval and review of data. Setup requires that WINDOWS 95 (r) or above, and Microsoft HYPER TERMINAL (r), are running on the computer. Easy data file review can be accomplished using Microsoft WORD (r), WORD PERFECT (r) or most any other word processor. The PDDR is also supported by Vital Sim's Data Display and Analysis Tool.
