H-Bridge Card supports PWM rates up to 30 KHz.
Press Release Summary:
Model 7I30 4-axis H-bridge card has maximum per axis current rating of 3 A and voltage rating of 48 V. Current limits of 1 A and 3 A are user selectable, as are fast and slow current decay modes. Chips use DMOS transistors and synchronous rectification. Encoder and index inputs are conditioned with RC filters and Schmitt triggers for high noise rejection. Controller connection is a 50 pin header that matches motion controllers.Original Press Release:
7I30 4 Axis H-bridge
The 7I30 is a low cost 4 Axis H-bridge card for use with Mesa motion control cards. The 7I30 has a maximum per axis current rating of 3 Amps and a voltage rating of 48V. Current limits of 1 Amp and 3 Amp are user selectable, as are fast and slow current decay modes.
The H-bridge chips use DMOS transistors and synchronous rectification for high efficiency and low power dissipation. PWM rates up to 30 Khz are supported. Encoder and index inputs are conditioned with RC filters and Schmitt triggers for high noise rejection.
The controller connection is a 50 pin header that matches the pinout of the Mesa 4I27, 4I34, 5I20 and 7I60 motion controllers. 4 latching Mini Mate-N-Loc connectors are used for motor/encoder connections.
When the 7I30 is used with the 4I34 card and SOFTDMC firmware, a high performance 4 Axis DC servo motion control system can be assembled for less than $190, and an 8 axis system can be made for less than $250 (all prices in 100s).
Like all Mesa cards, the 7I30 has a 2 year warranty and is available in industrial temperature range (-40C >> +85C) Price of the 7130 is $59.00 in 100s.
