SC-HCDA-ISO Serial Hall Call Driver Isolation Board
The SC-HCDA-ISO Serial Hall Call Driver Isolation Board is used on iControl AC and DC Sim-
plex and Swing car controllers. The isolation board is placed between the SC-HCDA Serial Hall
Call Driver (usually mounted inside the iPower Box) and the Serial Hall Call Input on the right
side of the iBox. Revision 6.0 and later of the ICE-IMP board incorporates the isolation circuitry
thereby eliminating the need for the SC-HCDA-ISO. Please refer to “Serial Hall Call” on page 5-
30 for additional information.
