OCB-8 Relay Boards
OCB-8 relay boards regulate floor control with the elevator. Each OCB-8 controls up to a maximum of eight (8)
floors. If the elevator control board regulates more than eight (8) floors, multiple OCB-8 control boards are
required. See Table 10 and Table 11 for ribbon cable elevator/floor assignments from the OCB-8 terminal to
the elevator control board terminal.
