1207B-4102 is the upgraded version of 1207/1207A DC Series And Compound Motor Controllers. 1207B-4102 is fully compatible with the old 1207/1207A controllers, ideal for replacing 1207A-41xx controller (for example 1207A-4107). For more details, please read carefully the 1207B Controller Manual (PDF format).
The 1207B controller accepts a variety of throttle inputs, through various combinations of its four throttle input pins. Throttle types:
- Type 1 = 5kΩ–0
- Type 2 = 0–5V, 3-wire pot, and electronic throttles
- Type 3 = 0–5kΩ throttles
