VARCO AUX SCR INTERFACE LOGIC ASSY NO 89130

VARCO AUX SCR INTERFACE LOGIC ASSY NO 89130 is a robust auxiliary SCR logic board for Varco top drive drilling control systems. This auxiliary SCR logic board processes trigger and feedback signals for SCR power drive unit. This auxiliary SCR logic board realizes auxiliary control logic for motor torque and speed regulation. This auxiliary SCR logic board adopts rugged PCB design for offshore drilling rig working environments.

This unit is a vital top drive control spare part for oilfield top drive maintenance. The top drive control spare part communicates with main SCR interface card to coordinate drive output. The top drive control spare part supports fault signal detection and alarm transmission for drilling motor. The top drive control spare part can replace defective original assembly to restore top drive operation.

It delivers reliable SCR drive signal conditioning for drilling motor power control. The SCR drive signal conditioning converts low-level logic signals to drive SCR power circuit. The SCR drive signal conditioning stabilizes current output during variable drilling load. The SCR drive signal conditioning protects the top drive motor from overload and sudden current surge.

VARCO AUX SCR INTERFACE LOGIC ASSY NO 89130 is installed inside top drive control cabinet. It is widely used for onshore and offshore rig Varco TDS series top drive overhaul, powered by 24VDC supply.
