The SI220 signal converter converts, multiplies and divides output signals into incremental pulse signals. It interpolates the output pulses per period of the input signal based on an adjustable multiplier and offers functions such as error detection and output. With adjustable parameters such as interpolation factor and glitch filter, the SI220 offers versatile application possibilities. Settings are easily made via DIL switches. The SI220 interface encoder replaces the old SI251 device.
