HTL signal converter SI220

incrementalDIN rail

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. • Encoder input with format SIN+, SIN-, COS+, COS-, REF+, REF- [1 Vss] • Control input „Error Release“ for PNP signals [10 ... 30 VDC] • Input frequency up to 400 kHz • Pulse output with format A, /A, B, /B, Z, /Z [RS422] or with format A, B, 90° [HTL] • Output frequency up to 4 MHz [RS422] • Control output „Error“ with push-pull characteristic, short-circuit-proof, [5 ... 30 VDC] • Power supply 18 ... 30 VDC • Snap-on housing for top hat rail (according to EN 60715) • Adjustable multiplier for interpolation rates from 1:5 to 1:50 • Adjustable divider 1:1 – 1:255 to reduce the output frequency
