These contacts are adequate for controlling locomotives in any scale, and they can be used to either “make” a circuit connection for the time duration, or to “break” a circuit connection for the time duration. The TD-1 requires an 11–15-volt DC power source for proper operation.  Although the power source does not need to be regulated, a filtered power source is preferred, and under no conditions should the input voltage exceed 15 volts. Since the accessory terminals of most power packs have outputs in the 16–18-volt range (or more!), they are not a good choice for powering the TD-1 (see POWER SUPPLIES section). The Trigger Terminals on the TD-1 require a momentary or continuous connection to ground [-] to initiate the timing sequence.  This connection can be supplied by most CIRCUITRON Detection Circuit outputs, reed switches, track contacts, pushbuttons, etc.  Once the timing sequence has been started, further inputs to the Trigger Terminals will be ignored.

This is very useful for automatic station stops or automatic downhill speed reduction.  The AS-1 offers distinct advantages over a dropping resistor for consistency of speed reduction independent of the load. 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). The output of the AS-1 is continuously variable from 0 up to within 3 volts less than the input voltage. The circuit board measures 2” x 3”. Note: The AS-1 does not incorporate any momentum or gradual slowing effects. The speed reduction is a fixed step. Flywheels in most locomotives\u003cbr\u003ewill reduce the abruptness of the change.","brand":"Circuitron Electronics","offers":[{"title":"Default Title","offer_id":46749958537447,"sku":"TOR5601IH","price":14.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/7798\/9095\/files\/800-5601-as-1-automatic-slowdown-circuit-mpm-hobbies.webp?v=1750786979"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/7798\/9095\/collections\/image_d0500179-09e6-4343-8146-62fdc15521aa.png?v=1774610566","url":"https:\/\/mpmhobbies.com\/collections\/in-stock-switches-actuators.oembed","provider":"MPM Hobbies","version":"1.0","type":"link"}
