Electric-Pneumatic Relays
Model Chart
Specifications
The electric-pneumatic relays are three-way,
two-position, electrically activated air valves for
use in pneumatic control systems where the
application requires a variety of switching,
diverting, or interlocking functions, actuated by an
electrical circuit. The R527 Series switches one
SPDT pneumatic circuit, while the R528 Series are
designed with DPDT pneumatic switching
(switches two independent SPDT pneumatic
circuits simultaneously).
Features:
• R527 Series provides SPDT pneumatic switching (N.C.,
N.O., C).
• R528 Series provides DPDT pneumatic switching (N.C.,
N.O., C), plus (N.C.2, N.O.2, C2). Switches two separate
circuits simultaneously.
• Manual/auto switch (permits control system testing without
starting and stopping electrical equipment).
• All ports clearly labeled. Ports align with MCS-S terminals.
• TAC PNEUMODULAR: Must be mounted on MCS-Socket
and used with MCS-EC electrical connector.
