About the 0-51865-16
0-51865-16 CLDT Current Regulator Loop Drive Board
The 0-51865-16 is a Reliance Electric board component. This circuit board is most often used within the company’s drive systems. It usually is marked with a Reliance logo, but in some cases may carry a Baldor-Reliance logo instead. In more rare cases, it may originate from Asea Brown Boveri/ABB. In each of these cases, the 51865-16 number will remain in the part ID.
The 0-51865-16 is a Current Regulator Loop Drive card. There are several versions of this board within the board series; please verify before placing your order the version that best meets your needs.
The 0-51865-16 includes two rotary dials on its front faceplate. These are labeled “current rate” and “current gain.” The faceplate also has a reset button, a red LED labeled “IET” and a four-position terminal strip with its own smaller cover. The terminals on this component are labeled 56, 161, 71, and 152. Each rotary dial connects to a potentiometer located on the circuit board. The screw terminals wire into the board’s surface using wired connections.
The 0-51865-16 has a conductive backplane on its rear edge. The edges of the board are ringed by a frame that supports ten vertically mounted auxiliary boards. These boards connect to the motherboard by pin connections. Most of the boards are populated by transistors, ceramic capacitors, polyester vinyl capacitors, and metal film resistors. Other boards may have disk capacitors and integrated circuits. There is an additional board mounted using standoffs and screw connections parallel to the motherboard to the top of the metal frame supports. This board has several transistors, an integrated circuit, metal film resistors, and several surface-wired connections. More information may be found through accessing Reliance manuals or series user guides.
