Connects to a PC or Laptop using our USB Cable or to any other host which incorporates an RS-232 serial port. Stack multiple cards together on the same port. Simple command strings sent from the host will set distinct DC voltage levels at the output channels. This voltage can be used for control of industrial equipment requiring a 0 to 10 VDC unipolar or bipolar control signal, as well as other uses. A built-in ramp generator is included. A change in voltage on an output can be configured to update immediately, or follow a slope at a user defined ramp rate. An external pause switch can suspend execution of a voltage slope at any point along the way for review or data collection. This module is ideal for complex multi-point cyclic operations without relying on host for timekeeping or conversion calculations.
