7I27 MANUAL 1

GENERAL

DESCRIPTION

The 7I27 is a dual 10A 40V Hbridge intended for motion control applications when

used with the MESA 4I27, 4I34M, 4I65, 5I20, or 7I60 motion control cards. The 7I60 uses
a 50 pin flat cable interface to the motion control card.

Motor power and motor connection are made with screw terminals. 5 pin

encoder connectors allow TTL encoders to be connected to the motion control system
through the 7I27 card

The 7I27 has overcurrent protection tp prevent damage to the Hbridge from

stalled or shorted motors.
