CURTIS 1204M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. 1204M controllers are updated versions of the popular 1204 controllers, with the added functionality of being programmable-via the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.
CURTIS 1204M controllers are the ideal solution for a variety of electric vehicle applications, including industrial trucks, personnel carriers, material handing vehicles, golf cars, etc.
Wiring Diagram
In this assemblage, the J5 terminal of new 1204M controllers is not activated. The controller wiring is same to the old 1204M controllers without J5 terminal.
