The SIN/COS encoder simulator is able to emulate incremental (20bit) or rotational (720kHz) encoder devices with differential sine/cosine tracks and signal amplitudes of 1Vpp

SIN/COS-encoder simulator with case
The SIN/COS encoder simulator is able to emulate either incremental or rotational encoder devices with differential sine/cosine tracks and signal amplitudes of nominal 1Vpp with 2.5VDC offset. A variation of the external termination resistances leads to a different signal amplitude from 0.6Vpp up to 2.0Vpp. It is possible to simulate impulse rates of up to 720kHz (rotational device simulation) or 20bit positions with one out of four fixed frequencies (incremental device simulation). For this case there are three blocks of DIL switches to control the frequency or the position. All signals and supply voltage are pluged via one 15pin SUB-D header. For quick connection there is optionally a SUB-D / skrew header adaptor available. An extra output can be used for driving external periphery (e.g. relay, accustical or optical devices).

There is also the possibility to remote control the SIN/COS-encoder simulator via serial interface (RS232-TTL) or via USB/RS232 adaptor, that can be connected to a PC. With a predefined data structure the user is able to transfer data patterns instead of using the DIL switches. It is also possible to transfer timing variable data (driving profiles). Even a wobble generator can be configured. Therefore the SIN/COS encoder simulator can be integrated into test equipments. Ing.-Buero Kirchen offers a demonstration software (free of charge) for WIN OS.
