2.2.3 Handling of double-acting reversing relay
A reversing relay is used when a double-acting actuator is used.
■ What is a reversing relay?
The pressure (POUT2) of the reversing relay’s output air (OUT2) is expressed in the fol-
lowing formula.
OUT2 = P
SUP
− OUT1
■ Reversing relay attachment
Detach the dustproof plug on the air piping connection.
Using sealing tape, connect the joint of the reversing relay to the output air port.
