SinCos Interpolator with Incremental Output (HTL / RS422)

The SI220 is the successor of the SI251 and converts sine-cosine encoder signals into incremental pulse signals with adjustable interpolation, multiplier and divider.

• 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
