Proposed Standard
Aaron Gonthier wrote 22 August 2019:
- I am working on a standard for locomotive control wiring for battery electric locomotives. It uses a premade Ethernet cable to go from the motor controller (or other control device) to the handheld throttle. The purpose of the standard is to make it easy to change out a broken cable or swap handheld throttles, cables and controllers from one locomotive to another with a minimum amount of rewiring. Ethernet cables are available most places in North America, from big box stores to convenience stores. They work with analog or digital control systems and allow for basic controls and a minimal amount of electronics in the handheld throttle.
- Having only the essential controls simplifies wiring, with only throttle, forward/reverse, horn and optional brake controls. Lighting controls can be on the locomotive or integrated with the reverser controls using a relay on the locomotive.
- My hope with this proposed standard is to make it a little easier for people building and maintaining battery electric locomotives. Your input is appreciated.
