RoboClaw 120A/160A/200A Dual Channel Motor Controller Data Sheet

Contactors, Relays and Solenoids

As a safety precaution a contactor, relay or solenoid with the proper ratings for the planned load should be used (RY1).

The disconnect devices contacts should be rated for the total current output of both motor channels combined. The

disconnect device can be controlled by the DOUT pins or a simple manual switch.

The DOUT pins are designed to control inductive loads. They can be toggled by external user commands. The wiring

diagram below illustrates a basic wire scheme using a contactor as the disconnect for main power. The DOUT controls

the ground to the relay coil. The positive terminal of the relay coil can be connected several ways depending on its rated

voltage. The diagram below shows a 12VDC logic battery and a contactor with a 12VDC coil. However if the contactor coil

is 5VDC then regulated output from the BEC should be used. The main battery can also be used as the power source to

energize the contactor coil.
