The DMC - Digital Valve Positioner is used in our flow control valves to proportionally position valve actuator between full open and closed positions via a 4-20mA or 0-10Vdc input signal. The card has been designed to be extremely easy to setup utilizing an on board microprocessor to store the zero and span positions with a simple button touch. It isn't necessary to cycle back and forth to set the zero and span. Local control switches on board allow for precise setting of the valve/actuator. Once you have the positions desired, simply store them in memory.
• Zero and Span Digital setup (no trim pots to adjust)
• 4-20mA or 0-10Vdc input - Jumper selectable
