Reversing Relay
Model Chart
Specifications
The reversing relay is a proportioning device
designed for use in pneumatic control systems
where the application requires the reversing of a
proportional signal from a controlling device. The
R516 branch line pressure decreases in direct
proportion to an increase in input signal pressure
and also amplifies the volume of air available for
the final control device, thereby minimizing system
lag.
The unit is factory calibrated to decrease the
branch line pressure from 16 psig to 0 psig as the
signal pressure increases from 0 psig to 16 psig.
Features:
• Clearly marked connections eliminate the need to
memorize port numbers: M (Main), B (Branch), and S1
(Input Signal).
• A bias adjustment is provided which can be used to
advance or retard the output signal as required for specific
applications (refer to Figure 2).
• The R516 may be used as part of the TAC

, panel-mounted, modular control
system, or individually, using a K502 manifold backplate
and its barbed tubing connections or MCS-Socket.
• Ports align with MCS-S terminals.
