Features & Benefits
  • Significant reduction of redundant channel switchover times from 12-13 seconds to 500 ms
  • Increased safety and product integrity through double-sealed protection that isolates the controls compartment from corrosive or severe environments
  • Absolute encoders with built-in self-test (BIST) capability that switches to redundant circuits in the event of a single sided failure, allowing actuator to continue operation while highlighting the need for inspection
  • Optional 4th conduit for both MX and QX providing the user with dual conduits for network redundancy – one for ingress and one for egress.
