Abaco Systems / SBS / Greenspring IP-Quadrature Four Channel Decoder IndustryPack

The Abaco Systems IP-Quadrature is a four-channel IndustryPack decoder module purpose-built for position and motion control applications requiring high-resolution incremental sensing. Each of the four independent channels delivers 24-bit resolution and operates as either a dedicated quadrature decoder or general-purpose counter, making it adaptable to diverse encoder and timing measurement tasks.

Technical Specifications

• Four independent channels


• 24-bit resolution per channel


• Count frequency: 0 to 10 MHz


• Dual-function operation: quadrature decoding and general-purpose counting Signal Input


• Differential or single-ended input modes


• RS-422 compatibility


• TTL/CMOS compatibility Programmable Control


• Mode selection


• Polarity configuration


• Interrupt generation


• Read-on-the-fly capability

Key Features The module accommodates both differential and single-ended input topologies, allowing integration with standard industrial sensor outputs. Programmable polarity and mode settings enable flexible encoder configuration without hardware modification. Interrupt support facilitates real-time event notification in motion control loops. Read-on-the-fly operation permits continuous count access without halting acquisition, critical for live position monitoring in closed-loop systems.

Typical Applications The IP-Quadrature targets incremental motion sensing across industrial automation and precision positioning. Shaft encoders ranging from 512 to 2048 counts per revolution integrate directly. Linear encoder applications benefit from resolution capabilities down to 0.005 inch per count, enabling sub-micron displacement measurement in machine tool feedback and robotic arm positioning.

Compatibility & Integration This IndustryPack module operates within IndustryPack carrier systems and compatible user-provided equipment. Proper carrier selection is essential - connection to incompatible hardware may cause serious damage. The standardized IndustryPack form factor ensures mechanical and electrical compatibility across qualified carrier platforms.
