236-233 and 236-353 Signal Color Test Units

Train traffic has condensed the time available to maintainers to conduct tests. Sometimes the dispatcher calls for the track back before the tests are completed. The S&C Signal Color Test Units can substantially reduce the time it takes to conduct any test that requires confirming which signal has been lit. With our Test Units, verify the field aspects, then do your work. No need to have a second person “calling colors”. No need to go outside and look. Saves the same amount of time and manpower when cutting over new-construction signal systems.

These test units are designed and built to provide reliable, accurate reporting of signal aspects from within the bungalow. Our Signal Color Test Units are electrically sound: are reverse polarity protected; Red has a discrete ground, other colors share a ground; very high internal impedances preclude crossover voltages; plugs are wired in parallel; and LED “signals” on Test Units bridge energy from the signal lamp river source, insuring that LED’s reflect the aspect being displayed in the field signal head and avoid becoming an additional or shunting load on the circuit.

Choice of two signal configurations (2 and 3), two light output voltage ranges (10-12VDC and 10-50VDC) and three connecting wire lengths (2, 4 and 8 feet long)
