TTL-encoder simulator with case
The TTL encoder simulator is able to emulate incremental encoder devices with differential A,B,Z tracks and impulse rates of up to 150kHz. For this case there are three blocks of DIL switches to setup the output data signal - a 12bit impulse count per revolution (CPR up to 4095) and a 11bit number for a revolution per second (up to 2047). The upper bit controls the direction CW or CCW. The Z-track (index track) comes - if used - once per revolution. 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 TTL-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).Therefore the TTL encoder simulator can be integrated into test equipments. Ing.-Buero Kirchen offers a demonstration software (free of charge) for WIN OS.

The TTL encoder simulator is also available for high voltage output signals up to 24V (instead of 5V). (see HTL encoder simulator). An other option is to generate and output a single 20bit position with 4 choosable clock rates.
