Quadra-4 by Versalent
This small USB 2.0 compatible (Full Speed) servo interface module provides feedback and drive signals to support up to 4 independent servo loops. Offers 4 incremental (quadrature) encoder interfaces which accept differential, single-ended or open-collector signals and each encoder can be independently configured for X1, X2 or X4 operation. Operates with 2V to 12V encoder signals. Each axis offers a 32-bit up/down counter with digital filtering that can accept encoder signals up to 3 MHz. Programmable 100 ohm terminations on each differential input pair. The 32-bit counter value at which the encoder index pulse occurs can be stored, or optionally the up/down counter can be cleared when the index occurs. Quadra-4 also offers 4 analog outputs which can be used to drive motors or other actuators as well as 8 general purpose digital I/Os which can be used for a variety of signaling functions. The digtial I/Os can be independently programmed as input or output. Each analog output is driven by a 10-bit DAC with range configurable as 0-10V, -5V to +5V, or -10V to +10V. Includes 6-foot detachable USB cable and 5V 1A AC wall-adapter. Optional DIN rail mount available. Size -- 6.5" X 4.5" X 1.75" Host Performance Considerations |
