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