CURTIS 1204M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. They are updated versions of the popular 1204 controllers, with the added functionality of being programmable—via the 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.
1204M-5203 is the new upgraded version of 1204M-5201 DC series motor controller, with new J5 terminal (reverse signal output / main contactor coil driver), and supporting more throttle types.
For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1204M/05M Manual before making the purchase.
If you need to modify any controller parameter, please send us a message with the list of parameters to be modified (Click here to download the parameter list of default setting of controller 1204M-5203 (PDF format)).
Wiring Diagram:
By default, the J5 terminal of new 1204M controllers is not activated. The controller wiring is same to the old 1204M controllers without J5 terminal.
If you want to activate the J5 terminal for using the Rev Input / Main Driver functions, please see the page 7 and 8 of 1204M / 1205M controller manual (PDF format).
