We Are Just A Phone Call Away

Signal Color Test Units

During FRA testing and other maintenance procedures, one man can know signal colors in the bungalow.  There is no need for a second man to call colors or for the lone worker to spend a lot of time walking back and forth between signals and the control point house.  With this product,  verify your connections by observing the field aspects, then go to work. Two models of Signal Color Test Units are available:  a version that simulates two 4-aspect signals and one that simulates three 4-aspect signals.  Each model is available in two wiring configurations:  Pos Break – Neg Common and Neg Break – Pos Common.  Also available:  a 50 Volt Power Interface to allow the Color Test Units to work with electronic interlocking products with lamp outputs of 40-50 volts.  A separate common is provided for the Red signals.  Both models work with either AC or DC lamp voltages.  A unique hanger at the top of the unit housings allows the user to suspend his Test Unit from any convenient AAR/RSA terminal so he can see the color displayed at a glance.  The hanger can be bent, or rotated (360 deg.) to achieve an effective viewing angle.  Three Cord Set lengths are available, 2 feet, 4 feet and 8 feet, all with heavy-duty, keyed plugs to prevent mistakes in hooking them up to the Color Test Units.  Kits are available with HD carry bags sized to accommodate two Test Units or one Test Unit and one Power Interface and cords in lengths ordered.
