Retrofit Guidelines
Gate Interface to Non-
Rockwell Power Module,
Retrofit
To interface to the SCR gates of a “non-Rockwell” power module, any existing
gate couplers in the power module should be replaced with the Rockwell
Automation gate couplers. This will greatly simplify the gate interface because the
characteristics of a standard Rockwell Automation interface are already defined.
There may be unique cases where there is a need to re-use existing gate coupler
hardware in a non-Rockwell power module - if this occurs, consult with
Development Engineering.
The diagram in Figure 26 shows a gate interface where the gate coupler boards are
individually mounted to accommodate physical constraints that may exist in the
assembly. A bracket, 608877-6A, is used as a landing point for the gate cabling.
Between the Gate Amplifier and the 608877-6A bracket the SD3K-
CBLFWDPMxxx (or SD3K-CBLREVPMxxx) cable is used. The flange of cable
SD3K-CBLCANNONxxx is mounted to the 608877-6A bracket. The opposite
end of the cable has box connectors that plug into the gate couplers. The output
of the gate couplers are connected to the SCR gates using cable SD3K-
CBLBOXA048 (or SD3K-CBLBOXB048 for S6R). The SD3K-
CBLBOXA048 cable has box connectors on one end to interface with the gate
coupler output and “pig-tails” on the SCR gate side of the cable for connection to
a terminal board. The SD3K-CBLBOXA048 and SD3K-CBLBOXB048 cables
for the S6R are pre-labeled as forward and reverse. They are 48 inches long and
are cut to the required length when installed.
