WS Position Sensors Output Specification TSSI
* 4096 counts per revolution (12 bit), 4096 revolutions (12 bit) * No Loss of Data at Power-down * Easy to Connect to PLC's with SSI Input Circuit Description
The sensing device of the SSI is a 24-bit absolute multiturn encoder. The position information is given by an analog/digital converter output serialized as a data word. The processing unit (PLC, Microcomputer) sends pulse sequences which clocks the data transmission at the required transfer rate. With the first falling edge of the pulse sequence the position of the sensor is recorded and stored. The following rising edges control the bit-by-bit transmission of the data word. After a delay time the next new position information

The sensing device of the SSI is a 25-bit absolute multiturn encoder. The position information is given by an analog/digital converter as a serial data word. The processing unit (PLC, Microcomputer) sends pulse sequences which clocks the data transmission at the required transfer rate. With the first falling edge of the pulse sequence the position of the sensor is recorded and stored. The following rising edges control the bit-by-bit transmission of the data word. After a delay time the next new position information will be transmitted.
