The A2081 is a multi-purpose device that controls analog and digital inputs and outputs with a LCMX02-1200ZE programmable logic device by Lattice semiconductor. The A2081 combines elements of the A2057 input/output head and the A2060 programmable logic head (which we often use in tandem) on one board.
