The system is compromised of a dedicated device controller and a 5-ported, 3-position, closed-center directional valve. The multiple feedback design system controller requires a minimum ±12 Vdc at 25 W or 1.0 A power source, and accepts a 4 to 20 mA, 0 to 10 Vdc or ±10 Vdc command signal input from a variety of sources including PLCs and computers. Convergent controller circuitry provides real-time command and feedback signal monitoring with a <100 µs response time. It is rated for operating temperatures from -25&#176 to 85&#176C.
