About the 0-51865-14

0-51865-14 CLDA Current Loop Driver card

0-51865-14 belongs to a series of Reliance Electric boards.  This component may be used within Reliance Electric drive systems.  Depending on the year of its manufacture, it is possible your board is marked with a different manufacturer, including Baldor-Reliance and ABB.  The part number of 0-51865-14 should remain the same.

The 0-51865-14 functions as a Current Loop Driver module.  There are two primary parts to this. The first of these is a narrow front faceplate with two connector screws that hold the module in place in the rack.  The faceplate includes a single rotary dial connected to a potentiometer located on the PCB. This dial is labeled current gain. The faceplate connects to the second major part of the module, the circuit board, by three screws.

The circuit board portion of the 0-51865-14 is marked by a grid pattern across its surface.   Most components are not marked by reference designators; however, TP test points are marked. Other components on the board include  thirty integrated circuits, capacitors, transistors, resistors, a potentiometer, and diodes. Integrated circuits include analog SPSTs, analog comparators, analog D flip-flops, and analog operational amplifiers.  The rear edge of the board extends and is covered in conductive tabs.

Reliance publications like user guides, manuals, and data sheets can be used to access more information regarding the installation, operation, or maintenance of the 0-51865-14.  These publications also provide information on handling and safety. Reliance Electric was responsible for providing technical support for this and all other boards in this series.
