DESCRIPTION
The RP670A/B are two-position switching relays. They
are used in pneumatic heating and cooling control
systems where a valve or a damper actuator must be
switched from one circuit to another. Fig. 1 and 2 show
approximate dimensions.
The RP670A has SPDT switching action and is gray in
color.
The RP670B has DPDT switching action; one SPDT
switch is gray and the second SPDT switch is white, as
shown in Fig. 2.

BEFORE INSTALLATION
CAUTION
Equipment Damage Hazard.
Switchover pilot pressure must be two-position,
not modulated, because during the switching, all
three ports of the switch (6, 7 and 8) are
interconnected.
INSTALLATION
Mounting
Suspend on tubing or mount on a surface. Mount on a
wall or panel with the 1-1/2 in. (38 mm) diameter spring
clip supplied (part no. 14003030-001). Obtain a no. 10
screw locally when using the mounting clip There are two
ways of surface mounting. See Fig. 3.
