SinCos Interpolator with Incremental Output (HTL - RS422) SI251
The SinCos Input Signal Converters:
- The SI251 SinCos Interpolator with Incremental Output (HTL / RS422) is an encoder interface that converts, multiplies, and divides the output signals of so-called sine-cosine encoders and comparable measuring systems into incremental pulse signals.
- From each period of the incoming sine-cosine voltage signal, a corresponding number of output pulses is interpolated, accounting for an adjustable multiplier.
- These can also be split before output if needed.
SinCos Interpolator with Incremental Output (HTL/RS422):
- Format for encoder input: SIN+, SIN-, COS+, COS-, REF+, REF- [1 Vss].
- "Error Release" control input for PNP signals (10–30 VDC).
- The input frequency is up to 400 kHz.
- Format for pulse output: A, /A, B, /B, Z, /Z [RS422].
- Pulse output format: A, B, 90° [HTL].
- Output frequency: up to 100 kHz [HTL], 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 the top hat rail (EN 60715).
- Adjustable multiplier for interpolation rates from 1:5 to 1:50.
- Adjustable divider (1:1–1:28) for reducing output frequency.
