The 193X726BAG01 is a Driver Coordination Card manufactured by GE for DC drive systems like the SCR Drive or the Speed Variator Drive. Both of these systems are closed loop and adjustable speed. While they can be used for general purpose systems, they are often used for machine tool control.
The 193X726BAG01, like many circuit boards in this series, has an attached front panel with an ergonomic handle to help with the removal or insertion of the drive from industrial rack systems. This makes it easier to handle the board during scheduled maintenance or to remove it from the rack system if it needs to be replaced. The front panel has four openings, two of which have been closed by removable plugs. One is left open and the last is populated by a rotary dial. The opening is labeled ‘voltage limit’ and the dial is labeled ‘current limit.’ Both of these line up with rotary potentiometers that are attached to the circuit board.
The 193X726BAG01 is built with two circuit boards. The upper board is attached to the lower using three screws inserted into standoffs. The lower board holds the majority of the components, including the previously mentioned potentiometers. This board is also populated with a number of resistors made from metal film and carbon composite material. Some of these components are mounted vertically. The board has diodes and capacitors. Components may be numbered but do not carry a reference designator.
