The SP-110996 is a spare part that is manufactured and designed by Allen-Bradley specifically to use with the pulse board of the 1395 series. It is specifically an armature for the pulse board of each drive. The Allen-Bradley SP-110996 armature provides the required isolation for the gate pulse circuit and at the same time, it provides protection to all the electronic and fragile parts of the pulse board and the SCR modules. This armature is sort of an electronic base that allows electrical connections to both the pulse board and SCR modules. Pulse boards and SCR modules malfunction are notorious for erratic motor operations and it can also be found on blown protection devices. This SP-110996 armature not only offers protection but a special place to attach the pulse board and preserve the correct functioning of the board and all the other parts that are involved with it.
