Synchronous serial interface ssi is a widely used serial interface standard for industrial applications between a master eg. Quadrature encoders have dual channels a and b phased 90 electrical degrees apart.

Ssi encoder wiring diagram. If you have tested another kind of encoder please help us to inform the community by letting us know your encoder model and result by dropping a message into granite devices support.

It shows the components of the circuit as simplified shapes and the capacity and signal associates surrounded by the devices. Wire draw encoders consist of a wire draw mechanism and an encoder. Clock frequencies can be as high as 15mhz. Ssi encoders use two twisted pair wires plus two wires for power.
Sicks wire draw encoders support a large selection of interfaces and facilitate easy system integration for applications in challenging industrial settings. Ssi encoder wiring diagram calt hae18 12 bit hall magnetic angle rotary encoder ssi absolute. This facilitates positioning on linear measuring paths. A single channel encoder often called a tachometer is normally used in systems that rotate in one direction only and require simple position and velocity information. Controller and a slave eg. The data rate of ssi protocol encoders depends on both resolution and cable length.
The rotation of the drum which is proportional to the length being measured is recorded and output by an encoder. About the module the 1734 ssi module collects serial data from industrial absolute position encoding sensors that use a standard ssi protocol. Ssi encoder cabling and data rate.

Ssi encoder wiring diagram wiring diagram is a simplified pleasing pictorial representation of an electrical circuit.
However as clock frequency increases the maximum cable run decreases a limitation common to all protocols. Ssi is based on rs 422 standards and has a high protocol efficiency in addition to its implementation over various hardware platforms making it very popular among sensor manufacturers. Incremental encoders are available in two basic output types single channel and quadrature. Wiring of ssi depends on the variant of ssi protocol present. Encoder wiring schemes can be unique to each encoder and one should follow the diagram or pinout designated on the encoder datasheet. The figure below shows the block diagram of the technology module with one connected ssi absolute encoder.
Multi channel differential encoder wiring with commutation tracks can have up to 14 wires and miswiring can result in signal issues such as deformed pulses low signal amplitude and shorted connections.
