4 입력 USB 인코더 리더
(PhidgetEncoder HighSpeed 4-Input)
개요
- 본 제품은 다양한 종류의 기계식 및 광학식 인코더와 사용이 가능한 제품으로 인코더 출력을 읽을 수 있는 제품입니다.
- 4개의 인코더를 동시에 읽을 수 있으며, PC에서 인코더 데이터를 확인 가능합니다.
- The PhidgetEncoder Highspeed 4-Input can be used with a wide assortment of mechanical and optical encoders. The encoder should be of quadrature output type, indicating that there will be two quadrature output channels (usually labeled A and B) and an optional third output channel to signal when the index pin (a reference point for zero position or a complete revolution) has been reached.
The PhidgetEncoder Highspeed 4-Input is able to read four encoders simultaneously. Encoders are not powered up until all initialization of the device is complete. It is possible to enable some or all encoders, depending on how many of the channels are being used. This can also be used to reduce power consumption when certain encoders are not needed.
The PhidgetEncoder Highspeed 4-Input has the added ability to time the duration between a group of quadrature changes. The time is returned in microseconds. This time value can be used to calculate velocity and acceleration.
Both mechanical and optical encoders are available, with optical encoders dominating at > 100 counts per second. Review the data sheet for the encoder you are planning to use to ensure it is compatible with the PhidgetEncoder Highspeed 4-Input. Almost any incremental quadrature encoder will work but it is important to verify this before connecting it to the Phidget. Absolute encoders will not work with this device. Ideally, you should choose a quadrature encoder with a 5-pin output and the following pinout in order to be directly compatible with the 1047.
This particular revision of the 1047 has improved power switches to enhance system stability when turning off and on separate encoder inputs. It also has updated firmware with a few minor bug fixes.
