Description

Model 61H F/R Booster Relay

The Siemens 61H F/R Booster Relay has been designed to be used in industrial high-speed control applications, producing a high-volume boosting action. This booster relay?s primary purpose is for use with valve positioners, although it can be used by itself for the high volume of air it can control.

The relay contains an integral stabilizing bypass valve which eliminates the need for an externally piped bypass. The bypass opening is controlled by a screwdriver adjustment in the body of the relay which accommodates easy tuning for an optimal dynamic response. Opening this booster valve improves the stability of the positioner/relay/actuator circuit. This relay is not normally used in measuring circuit applications.
