IO401
Flexible 6-channel 32-bit counter module for quadrature and SSI decoding
This module provides 6 channels of 32-bit counters to either connect incremental encoder sensors or absolute encoder sensors. In the case of incremental encoders quadrature decoding (1x, 2x, 4x) is used to acquire the position and deal with Index information. In the case of absolute encoders the Standard SSI (Synchronous Serial Interface) protocol is used to acquire the position. Each of the 6 channels can be individually set to work as a Quadrature or an SSI decoder. The available resolution is 32 bits (depth of counter). Also, the channels are all isolated and work with encoders which either have a TTL or a RS422 (differential) signal interface. The included xPC Target driver blockset allows reading channels (positions) indidually at different sample times or combined (simultaneously latched).
Highlights
General
- 6 isolated channels
- Quadrature or SSI decoding, individually selectable per channel
- 32-bit deep counter
- Supports encoders with TTL (single-ended) or RS422 (differential) signal interface, selectable individually by on-module DIP-switches
- Driver blockset support individual or combined (latched) reads
Quadrature decoding
- 1x, 2x, and 4x quadrature mode for incremental encoders
- Software-selectable signal (A, B, Index) polarity
- 5MHz maximum A/B input frequency
- Reference (Index) preload and initialize functions
SSI decoding
- Supports Standard SSI protocol for absolute encoders
- Supports single-turn and multi-turn encoders with data word lengths of up to 32 bits
- Controller mode where SSI channel creates clock pulses of 1µ to 15µs in steps of 1µs
- Listen-only mode where remote entity creates SSI clock pulses
- Binary or Gray code data word decoding
- Odd, Even, or None parity
This I/O module is in the PMC form factor and can be used in any of the Performance, Mobile, and Modular or application optimized real-time target machines from Speedgoat (exception: Classic real-time target machine). The PCI bus of this module runs at 32-bit/33MHz.
Each module comes with an external shielded round 68-pin I/O cable and a 68-pin screw terminal block for easy access of all physical I/O signals. An xPC Target driver block library is also part of the package.
