The PTC Model 4 (Programmable Turntable Controller) is a user programmable turntable indexing system for use in new or existing N, HO, S, O, and some G scale turntables. The turntable’s indexing positions are programmed into the PTC by the user, who “teaches” the PTC where the lead and service track positions are. The PTC does not use infrared diodes, tab stops, or any mechanical methods for indexing. Once programmed, the PTC remembers the user’s track locations– even when the system power is turned off. During operation, the user selects the desired lead or service track from the control panel. The PTC then automatically determines the shortest direction of travel, simulates turntable momentum by ramping up the bridge to a user-determined maximum speed, then ramps it down as it approaches the desired service or lead track location. The PTC then stops the bridge at the exact location desired, within 0.025 degrees.
The basic PTC is comprised of the Track Selector Module, Stepper Motor, Motor Mount Kit (optional), and Power Supply.
