Implementation of SSI Interface

Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications especially, rotary encoders. It is a point-to-point connection from a master (e.g. PLC, microcontroller or other control systems) to a slave (e.g. the rotary encoder).

How-to: 2 Point Operation of an Open Collector Switch Output

In this example, the switch point has been set to ‘Full Alarm’. By setting the switch point to 90% with an 80% hysteresis, the switch will come on at 90% and switch off at 10%.

SSI Hardware

SSI hardware is fairly simple. Just use any RS-422 transceiver to generate the differential signals from/to the microcontroller port pins. Keep reading to learn about the different implementations of SSI hardware.

MEMS Inclinometer Specifications

Inclinometers, also called tilt sensors, clinometers, or slope sensors, are designed to measure the angle of an object with respect to the force of gravity. These tilt or level meters determine the pitch and/or roll angle and output these values via the appropriate electrical interface.
