About the 0-51811-1

The 0-51811-1 is a TSTB Control board by Reliance. The circuit board has a faceplate labeled TSTB across the top. Below that is a DC Voltage meter on the bottom left it says type and, on the bottom, right it says DW-90. The center of the meter is zero. Below the DC Voltage meter is a variable resistor. The numbers around the knob of the variable resistor go from one to twelve. Then there is a line that links numbers seven through eleven and on the inside of that line are more numbers 1.5, 6, 16, and 60. On the bottom left under the variable resistor is says SCALE (+) on the bottom right under the variable resistor is says TEST (-). In the center of these two words is a toggle switch. Under the toggle switch is another variable resistor with a black dial. This time the numbers are printed on the dial. The variable resistor is labeled Test Signal. Below this variable resistor is two eye hooks. The left eye hook is labeled Output and the right eye hook is labeled Common. At the top and bottom of this circuit board is the screw in anchors that secure it into place. The circuit board attached to the faceplate has three red colored pieces, four green colored pieces, and two black colored pieces. All of these are along the top edge of the circuit board. The rest of the circuit board is filled with all the wires that are connected to the DC voltage meter, the toggle switch and the two variable resistor knobs.
