About the 0-51865-6
0-51865-6 CLDB Current Loop Driver
The 0-51865-6 is a Reliance Electric circuit board with an attached faceplate. This component is typically used within Reliance drive systems. Most often this component is marked as being made by Reliance, but in some cases, it may have logos from either ABB/Asea Brown Boveri or from Baldor-Reliance. The 51865-6 number will remain as part of the id number in all these situations.
The 0-51865-6 functions as a Current Loop Driver card. The faceplate has two rotary dials located one above each other. These are labeled “current rate” and “current gain.” The faceplate includes two set screws that lock the component into place when it is inserted into a rack system. These are located at the top and the bottom of the faceplate.
The 0-51865-6 has a grid pattern across its top surface. The board has a metal frame with cross supports that rings the entire board. This support is designed to support auxiliary boards like gate drivers if they are installed. These boards are installed at a ninety-degree angle into pin supports located on the board’s surface. The edges of the board insert into scores made in the cross supports.
Other components located on the 0-51865-6 include various capacitors, including ceramic disk, polyester vinyl, and those made from aluminum electrolytic material. The board has both CCR and metal film resistors. Surface wiring is used. There are several transistors and two integrated circuits. More information may be found through Reliance manuals and user guides. Such publications were provided by the OEM as ongoing technical support.
