Connecting Optional Signals

This section contains information about wiring optional NI 951x signals.

Connecting a Brake Signal

The NI 951x digital outputs do not provide enough current to drive typical motor brakes. For this
reason, the NI 951x digital outputs must

not

be used to directly control motor brakes. However,

you can use the NI 951x digital outputs to control external circuitry that does meet the higher
current requirements of motor brakes. Refer to the specifications for the motor brake to
determine the maximum current requirements. Use the following recommendations when using
an NI 951x digital output to control external circuitry driving the motor brake:
•

Do not exceed the maximum current specifications of the NI 951x digital outputs.

•

If the same power supply is used for the NI 951x module and the brake circuit, ensure that
the power supply meets the maximum requirements of both the NI 951x and the brake
circuit.
