The 7I33 is a 4 axis analog servo interfaces intended for operation with Mesa's Anything I/O cards in motion control applications. The 7I33 takes the PWM and direction signals from the Anythng I/O card and converts them to +- 10V analog output voltages for direct connection to analog input servo amplifiers. The 7I33 also conditions the encoder input signals with input filters for TTL inputs or RS-422 recievers for differential encoder inputs. The controller connection is a 50 pin header that matches the pinout of the Mesa's Anything I/O cards. Another 50 pin header is used for servo amp/encoder connections.
