The High Intensity, wide angle LED has a square base with a round dome lens protruding from it. If the base portion is painted black or silver, and the dome flattened slightly with a file, the resulting shape closely simulates a scale EOT device. The CF-1 is designed to be powered by a 9 volt battery and will provide up to 100 hours of flashing from an alkaline type. Refer to the section on HIDDEN ACCESSORY SWITCHES for a listing of switches that can be used to control the CF-1. Because of the relatively high voltage requirements, powering the CF-1 from track power is not practical, unless your layout utilizes command control. In this case, a CIRCUITRON PS-3 Power Supply will convert the track voltage to 9 volts in order to power the CF-1.

The DT-4 actually contains four completely independent detection circuits combined onto one circuit board. Each of the separate sections may be used alone or in conjunction with each other at various points on a layout. The DT-4 utilizes our proven OptoElectronic principle (see DETECTION SYSTEMS - AN OVERVIEW) and provides a signal at one of the output terminals whenever the corresponding Opto-Sensor is shaded from the ambient room light by a piece of rolling stock. Independent sensitivity controls are provided to adjust each of the 4 circuits to varying lighting conditions. The DT-4 can be used for any scale and will detect all powered and unpowered rolling stock with no modifications necessary. Each output on the DT-4 provides a connection to ?negative? (ground) when the Opto-Sensor is covered and the output is ON. Like all CIRCUITRON Detection circuits, these outputs will each control up to 250 ma. of DC accessories or lamps. The DT-4 is constructed on a 3? x 3? printed circuit board and requires a 6 - 20 volt DC power source. For greatest stability and ease of adjustment, the power supply should be filtered or regulated (see section on POWER SUPPLIES). One of the most useful applications for the CIRCUITRON DT-4 is to light panel lamps for spotting rolling stock in a hidden location. If the Opto-Sensors are installed at set intervals along the track, a train?s progress can be easily monitored on the control panel, even when it is completely hidden from view. In similar fashion, one of the DT-4?s OptoSensors can be located near the end of a blind siding. The output can be used to light a panel light, sound a warning buzzer, or activate a relay which will cut power to the track. Many modelers have found the DT4 indispensible when used in hidden staging yards. An Opto-Sensor placed at the end of each track, and another just beyond each fouling point gives clear visual indications of where trains are located and whether any are fouling the turnouts.

The BD -2 works by detecting the current drawn by a locomotive or lighted piece of rolling stock. Detection can be extended to un-powered equipment by using metal wheelsets with resistors connected across the insulator (any value between 4700 and 10,000 ohms should work well). The BD-2 senses detection by ?monitoring? the voltage drop across a pair of diodes. These diodes introduce a small voltage drop of 0.7 volts to the track. Although very slight, this voltage drop may be noticed when moving between blocks that have no detection and blocks protected by the BD-2. The simple solution is to install a pair of diodes wired in series with each of the un-detected blocks. An adjustment control is provided to set the sensitivity of the circuit and can be used to compensate for damp conditions, outdoor use, etc. At its most sensitive setting, the BD-2 is capable of detecting 100,000 ohms or less across the rails. The BD-2 also incorporates a turn-off delay of approximately ? second to prevent loss of detection due to dirty wheels, etc. The BD-2 will directly drive either LED-type or incandescent lamp, 2-color block signals and the outputs have a maximum current capacity of 250 ma. The circuit boards are designed for easy daisy-chain wiring of multiple blocks and will snap into a section of our PCMT (Printed Circuit Mounting Track) for simple installation. The BD-2 is constructed on a 2? x 3? printed circuit board and is available in standard 3 amp track power capacity (which is adequate for HO and smaller scales) and in a heavy duty 6 amp capacity version, the BD-2HD. Both circuits require a 10-18 v. DC power source for proper operation. The signal driving capacity of the BD-2HD is increased to 500 ma. per output and will work well with large scale equipment.\u003c\/p\u003e","brand":"Circuitron","offers":[{"title":"Default Title","offer_id":46689452654838,"sku":"CIR5502","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0504\/9925\/6496\/files\/bd-2-block-occ-det-crnt-s-318593.jpg?v=1748412342"},{"product_id":"sd-1-sig-drvr-3-asp-3lmp","title":"SD-1 SIG DRVR-3 ASP,3LMP","description":"\u003cp\u003eCircuitron 5510 @SD-1 SIG DRVR-3 ASP,3LMP\u003c\/p\u003e","brand":"Circuitron","offers":[{"title":"Default Title","offer_id":46689452720374,"sku":"CIR5510","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0504\/9925\/6496\/files\/sd-1-sig-drvr-3-asp3lmp-998807.jpg?v=1748412341"},{"product_id":"sd-2-3-position-semaphore","title":"SD-2 3 POSITION SEMAPHORE","description":"\u003cp\u003eUse with the Tortoise Switch Machine and an upper or lower quadrant semaphore-style signal. \u003cbr\u003e\nIncludes al the logic circuitry to drive the signal to all three positions.

When a resistor is used to drop voltage, the voltage drop will vary depending on the load. If the resistor is chosen to provide the proper speed reduction with a locomotive drawing 0.5 amps, for example, this same resistor may stop a different locomotive entirely if its current draw is 1.0 amp. The solid state circuitry on the AS-1 greatly reduces this problem, and one adjustment of the on-board output trimmer control will generally suffice for all loads. The AS-1 is bi-directional and simply connects in series with one of the track leads. Heat sinking is sufficient for controlling up to 2 amp loads and the AS-1 may be used with AC or DC track power (Do not use with Command Control).

This thin wire attaches to a compact actuator mechanism and is mounted beneath the turnout. It includes a spring wire and brass tube to transmit the motion to the points above. The mounting bracket (with TORTOISE™) may be secured in any position and up to 18\" away from the turnout points even above the layout inside a structure, if desired. The points actuating mechanism requires 1\/2\" clearance under the turnout sub-roadbed.
