PXI/PXIe 48-Channel Digital Output Module

The 40-412A-022 (PXI) and 42-412A-022 (PXIe) are 48-Channel Digital Output modules with high output voltage and current capability. The outputs can be used for high or low drive and each channel is capable of sourcing 0.4A from the high side or 0.1A sink on the low side. Accidental operation of both high and low side driver on the same channel is prevented by the supplied driver. Outputs are fully protected against over-voltage, over-current and thermal overload, ensuring robust and reliable operation in the toughest test environments. For high side driving, the voltage source is supplied externally, allowing the module to drive high capacity loads separate from the chassis power supply. For low side driving, the external source is not used and the module’s output operates an open collector or open drain driver.

The built in protection systems include an over-voltage clamp so the module can drive relay coils without the use of fly back diodes.

Connection to the module’s outputs is via an easy to use 78-pin D-type connector which is fully supported by a range of connector accessories.
