Servo Interface Includes 8 DAC Channels
Functioning in motion control applications, Mesa Electronics’ 7I65 8-axis analog servo interface works with 8 16-bit DAC channels. The component presents 8 TTL or differential encoder inputs, 8 12-bit + sign A-D inputs, 8 isolated motor enable outputs, and 4 isolated digital inputs. Analog outputs have software selectable ranges including -10 V to 10 V, -5 V to 5 V, 0 V to 5 V, and 0 V to 10 V. Analog inputs have software selectable ranges including -10 V to 10 V, -5 V to 5 V, -2.5 V to 2.5 V, and 0 V to 5 V. Input and output ranges can be selected on a channel-by-channel basis, and all analog I/O are galvanically isolated from system logic ground. A built-in watchdog timer, an on-card EEPROM, a 50 pin header matching the pin-out of Anything I/O cards, and 3.5 mm screw terminal-compatible plugs are included.
