Switching Relays
Application
These relays can be used for a variety of switching applications. Typically they provide control of line- or low-voltage
devices by a low voltage controller. See Table 1.

IMPORTANT: The transformer on the R182 can overheat when used with a series 20 thermostat if the
total resistance of the thermostat circuit exceeds
2.5 ohms. If the measured resistance of the thermostat (including thermostat wire and thermostat contact resistance) exceeds 2.5 ohms, add a 100 ohm,
10 watt resistor between the W and R terminals.
Table 2 gives maximum thermostat wire runs; if
longer runs are necessary, measure the resistance or
add a 100 ohm, 10 watt resistor across terminals W
and R.

MOUNTING
For replacement, mount the relay in the same location as
the old relay. If this is a new installation, locate the relay
vertically on a solid wall or partition as close as possible to
the device to be controlled. Select a location that is easily
accessible for installation and service.

NOTE: To reduce the possible transformer hum and relay
noise that is sometimes amplified by mounting surfaces
such as sheetmetal, plasterboard, and similar materials,
place rubber or felt washers between the case and the
mounting surface.

1. Position the relay and mark the mounting holes. See
Fig. 1.
2. Start a screw for the keyhole type mounting hole in
the upper right corner. Screw it down within about 1/8 in.
[3 mm] of the surface.
3. Hang the relay on the screw, position the case, and
start the bottom screw.
4. Tighten both screws.

See Figs. 2 through 9 for hookup diagrams for these
relays. When two or more devices are to be controlled in
parallel, the total current must not exceed the relay load
rating. Fig. 11 is an internal view of the RA832A showing
terminal locations and barriers.
Never connect load terminals to a load that takes more
current than the amount listed in the electrical ratings on the
relay.

1. Never use oil on any part of the relay coil or contacts.
2. Keep the cover on the relay during normal operation
and remove only for service and checkout.
3. Relay contacts require no cleaning; they are arranged
so they close with a wiping action and are self-cleaning.
The contacts may turn black after being in service for some
time; this discoloration does not prevent proper operation.
4. After installation is complete, operate system through
at least one cycle from the controller to make certain the
relay controls the equipment as intended.
