EM-A24-PCI-SPF DC-Motor Driver module With Positioning Pulse Feedback

43,00 € /unit

EM-A24 is a DC-motor driver module, It's based on EM-241 driver card. This module is
PCB mountable with PCI express 98 connector and it needs a very small pcb area,
because it will be installed vertically. This module has effective H-bridge power stage. The power stage has low EMC emission and it can meet EMC directives for industry and household enviroments without external components. This is big benefit when integrated this module to the "motherboard". Module has two pwm frequency option 2kHz offer more current, and 16kHz is noiseless. The board version v4 and later has added Rs-485 bus. This bus can be used to control, monitoring and also parameter setting for device.
