Pilot operated, multi-stage 1:1 relay
The Type 200 Precision Air Relay is a pilot operated, multi-stage 1:1 relay with a positive and negative bias adjustment capability. It accurately reproduces a signal pressure plus or minus the bias setting with consistent reliability. Output control and stability are maintained through a high gain servo balanced control mechanism which is activated by a highly sensitive stainless steel measuring capsule.
