GE193X Series Coordination Board, DC Drive Control and Interface Card, G02 Variant

Product Description

What this part is

A General Electric 193X701BBG02 Coordination Board. It belongs to GE’s 193X family of plug-in control cards used in GE industrial drive and process control cabinets, and its role is coordination: it acts as the control and interface card that sequences the drive’s regulator cards and ties them together into one working system.

It is one plug-in card out of a cardset in a GE drive or control cabinet, and it functions in that cabinet alongside the regulator, field control and firing cards it was designed to work with. It handles logic-level signals and does not switch motor power.

Decoding the part number

193X: GE’s drawing prefix for this generation of plug-in control and regulator cards. The 193X family covers coordination, field control, firing, regulator and interface functions, and cards from within it are not interchangeable with one another. 701: the board drawing number, which fixes the function as coordination. BB: drawing revision letters. G02: group / variant number. G01, G02 and G03 of the same board are built for different cabinet configurations and firmware.

What a coordination board does in practice

In a multi-card GE drive, the speed regulator, the current or armature regulator, the field control card and the firing circuits each perform one function, and the coordination board arbitrates between them: enable and disable in the right order, hand-off between regulating modes, and propagation of a fault condition so the whole drive trips together rather than one card at a time.

Interchange references

The whole string, letters and G-number included, identifies the card. Other 193X cards perform different functions; 193X532 is a motor field control card, a separate role. Also written 193X-701BBG02, 193X-701BB-G02, 193X701BB G02, 193X 701 BB G02 and 193X701BBG2. The GE number marked on the board itself is the ordering reference.
