Introduction to the Controller

Controller Configurations

The controller converts single phase A C line power to adjustable D C
power for either speed or torque control of D C motors rated 1/4
through 2 HP . The controller is specifically performance matched to
Reliance D C Motors to provide a compact controller/motor package. It
will operate all Reliance 1/4 through 2 HP permanent magnet or wound
field D C motors with compatible armature and field voltages.
The controller is available in a wide array of application specific
configurations, in flat plate chassis or open chassis designs as well as
NEMA 12 or NEMA 4/4X/12 enclosure designs. Tables 2 1 through
Table 2 3 list available configurations.
Note: Oil tight and dust tight conduit hole plugs (part 197308A) are
standard on DC2 NEMA 12K designs. Conduit hubs are not supplied.
Note: Water tight conduit hubs are standard on DC2 NEMA 4/4X/12
designs. Additional conduit hubs for NEMA 12 or NEMA 4/4X/12
designs can be ordered by referencing Reliance Part Number
608826 2A.
Note: Models DC2 95 and DC2 97 feature a special 10 turn speed
potentiometer. Reference Reliance part number 600594 14SFX for
replacement.
Note: When the RE020 D C Tachometer is used, a controller isolation
transformer must be used. See Install a Disconnect in Section 3 of this
instruction manual for complete instructions.
