The ED3 is an LCD readout that serves as a position indicator or tachometer. The ED3 can display:
Speed or position of a quadrature output incremental encoder
Absolute position of a MA3-P/MAE3-P (PWM output) encoder
Number of digital pulse counts, or pulse rate, gated with a direction control
Seven 0.5" high numeric digits with blue backlight
Bidirectional counting, displays signed values from 0.000001 to 9999999
Three LEDs to indicate High, Match, or Low setpoints
Isolated SPDT relay output with programmable set points
Digitally filtered counting speed from 0 to 1.2MHz
Easy in-the-field programming of modes and parameters
Available with a single-ended (S) or a differential (D) interface
Supplies +5V power for an external encoder or inclinometer
Accepts power supply voltages from +7.5 to +24V
