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.
Features
* Adjustable from 30:1 dividing ratio to 1:30 multiplying ratio.
* Venturi aspiration system.

* Floating seal ring isolates control chamber.
* Panel or Line Mounting
Benefits
* Assures infinite pressure adjustments.
* Compensates for downstream pressure losses.
* Allows versatility in applications.
