Product Description

Inputs: 64 digital inputs (LS TTL) 4 encoder inputs (1x or 2x) 4 analog inputs (0-5V) 4 analog inputs can measure a voltage between 0-5V. A potentiometer can be connected directly to these inputs. The center wire is connected to the input pin and two other wires to ground and 5V connectors. 4 encoder inputs can be configured to work in 1X or 2X mode. Encoder inputs can also be used as pulse counters. In 1X mode A channel counts either rising or falling edges if B channel is connected permanetly to 5V or ground. In 2X mode card counts both rising and falling edges if the signal is connected to both A and B channel. All 64 digital 5V logic inputs are pulled up via LS TTL internal resistors. A simple switch can be connected directly between input and groud.
