EADAPT ENCODER SIGNAL CONVERTER

EADAPT Product Description

The EADAPT is an inline encoder signal converter that allows the user to invert or not invert any A, B, and Index encoder signals. The EADAPT can use this to invert the encoder's rotation sense. The input quadrature signals can be single-ended or differential. Single-ended inputs can have amplitudes up to 30V. In addition, the index can be optionally gated by both the A/B channels going low to get an index pulse that is at most one quadrature statewide. This feature is useful when using encoders with a wide index pulse that spans multiple quadrature states.

Encoder input signals enter through a 10-position pluggable screw terminal block. Single-ended encoders should be placed close (less than 2 ft. preferably) to the EADAPT on the input side to limit noise. The EADAPT output is made through a 10-pin latching connector compatible with US Digital encoder interface products. The +5VDC supply voltage for the EADAPT is supplied from the J2 output connector. Three LEDs indicate when the associated A, B, or Index outputs are high.
