TE Revolution decoders/receivers Overview: Note: this page is being updated to cover all the 1st and 2nd gen TE receivers. There are 2 basic kinds of decoders/receivers. The first is intended to go into the locomotive "onboard", has pins to plug into the Aristo socket, and is small. The current capability is good, 5 amps continuous, 8 peak. The second type has "evolved" from the original "Train Engineer Trackside" unit, which was intended to power a layout. The product has evolved to a board much smaller than the original 27 MHz equipment. The first of these for the Revolution system were sold just as a board, no case, and were eventually renamed to "super receivers" Onboard units: The original units were motor and lights only. Later Crest made them available with sound, first diesel, then later steam Trackside / "Super" receivers 57005 - Original Trackside receiver This unit had the terminal strip screws removed to allow wires to be soldered to it directly by the user. This is the original run, no case, no sound. They were originally called "Trackside" since they were intended to power the tracks like the original 27 MHz trackside units. Strange they were never in a case. 57005S - Trackside / with sound (PWC/PWM) Below is the original Super Receiver, note no mounting bosses for the fan. Shows the Crest logo Below is a picture of the 2017 model PWC (PWM) super receiver 15 amps (with fan on) Notice the nubs on the case for mounting a fan 57005S - Trackside with sound (Linear output) And below is the new 2017 Linear super receiver: 10 amps notice the fan mounting nubs Note that there are 3 output terminals on both super receivers. The center terminal is not used, and is for some future expansion, as of yet unannounced. You will also note that there is no external fuse, it is now internal, and the overcurrent circuitry has been beefed up, so the external fuse is not needed. The inputs are polarity sensitive as before, and never connect power to the outputs.
