* The SilverPak DE has the optical encoder option. The encoder can be used to monitor speed, direction, and distance of travel. A controller measures the process' speed by simply timing how fast the encoder supplies pulses. It determines direction by monitoring which channel (A or B) rises first. It determines distance traveled by counting the number of pulses sent since movement began.
