Two dc-dc converters are used to generate the internal logic voltages from a dc input of 24V ±20%.
The logic power rails are brought out on the front panel for analog sensors and associated circuitry.
These rails should not be used for machine I/O,
usr-V+ and usr-gnd should be used instead.
The controller has opto-isolation between the microprocessor controller and the inputs and outputs to
provide noise immunity required for industrial environments. The power supply unit inputs (24V dc)
include isolated grounds.
Using a power supply of 24V dc at 2A is sufficient to drive all the outputs at 50mA and with all the
inputs on.
- WARNING -
Applying mains voltages to NextMove BX (110V/220V) will damage the unit. Ensure that the
power input voltages comply.
