{"product_id":"circuitron-5615-tc-3-automatic-tortoise-control","title":"Circuitron 5615 TC-3 Automatic Tortoise Control","description":"This is Circuitron 5615 HO Tortoise control automatic. TC-3 Automatic Tortoise Turnout Control. The Circuitron TC-3 provides automatic activation of a Tortoise Switch Machine when used with a Circuitron detection circuit such as the DT-4. The TC-3 may also be used with Switchmaster™ and other brands of stall-motor switch machines that use the Hankscraft™ display motor. The TC-3 has two input control terminals and is used to force a turnout to a specific direction. One common application of the TC-3 is to provide a non-derailing function on a trailing point turnout. 2 Opto-Sensors from a DT-4 are used by placing one on each leg of a turnout a short distance ahead of the frog. A train approaching from either leg will pass over the respective Opto-Sensor, activate the DT-4 output sending a control signal to the TC-3 which will align the turnout so as to prevent a derailment. Pushbuttons may easily be added to the TC-3 so that manual control is maintained. The TC-3 requires a 12 - 18 volt DC input and is constructed on a 1½ x 3 printed circuit board.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Factory New (\u003ca href=\"#\" title=\"C-9: All original; unused; factory rubs and evidence of handling, shipping and factory test run.
