Opto 22’s SNAP-SCM-SSI Serial Module provides a communications interface between digital encoders and its SNAP PAC System I/O processors or programmable automation controllers. The module’s two isolated serial synchronous inputs (SSI) simplify acquiring data from optical and mechanical encoders and other types of linear and rotary transducers.
Accommodating an SSI clock frequency of up to 2.5 MHz, the module functions at cable lengths up to 500 feet, and can be configured for clock frequency, data bits (i.e., encoder resolution), time interval between data samples, and more. The module accepts input from either binary or Gray code encoders to process and communicate position-related data for several industrial applications.
