| | | Type SCC - 100 (Standard performance) Signal Order Code: -VM & VV Suffix Incremental sinusoidal signals ~IVpp, IIuApp This converter takes the TTL,RS422 differential quadrature output signals from the SHG and the MHG Newall linear encoders and converts these signals to analogue Sine and Cosine levels. The SCC-100 provides the conversion to both -IVpp and II|jApp standards. A digital reference marker signal is provided. Analogue Output Connections | | |
| | | Type SCC - 200 (High performance) Signal Order Code: -VP & VS Suffix Incremental sinusoidal signals ~IVpp The sinusoidal incremental signals are digitally derived but due to advanced processing a near pure sinusoid is produced for both the A and B signal channels.These channels are phase shifted by 90° and have a signal level of -IVpp differential when terminated using the recommended circuitry with a common mode voltage of 2.5V. The signal levels are maintained at all speed levels providing no loss of signal integrity with increasing scanning frequency. . , _ ... Connection Details | | |
