The 7I29 is a dual 22.5A 165V Hbridge intended for motion control applications
when used with the MESA 4I27, 4I34M, 4I65, 4I68, 5I20, 5I22, 5I23, or 7I60 motion control
cards. The 7I29 uses a 50 pin flat cable interface to the motion control card. The 7I29 is
a 2 Axis card but can connect to 4 axis/cable FPGA controllers, allowing 2 7I29s to share
a single flat cable from the controller.
Motor power and motor connection are made with screw terminals. 10 pin encoder
connectors allow TTL or differential encoders to be connected to the motion control system
through the 7I29 card
The 7I29 has overcurrent protection to prevent damage to the Hbridge from stalled
or shorted motors. Each channel has two user selectable current limit values, full (22.5A)
and low (11.25A)
The 7I29s control circuitry is galvanically isolated from motor power and has 2500V
RMS isolation for safety.
