The Fisher DVC2000 is a compact digital valve controller designed for pneumatic actuators on sliding-stem control valves. It uses a 4–20 mA input signal with HART communication and provides accurate positioning along with basic diagnostics. Its small size and simple mounting make it a popular choice for space-constrained applications and general process control where full-featured positioners are not required.
