Robertshaw 620-202 plug-in transformer supplies 24V AC secondary power from 120V for furnace and boiler controls. The secondary stays isolated from the power source and shuts down safely on overheating through a thermal fuse.
Non-polarized plug-in blades and #6-32 output screw terminals get it into service quickly.
