Figure 16: CT24-9-ASO Relays and Terminals
6.1 CT24-9-ASO Compatibility with CT24-9
It should be noted that the CT24-9-ASO has enhanced safety using safety relays on K6 through K9 and that the
Main Contactor relays K0-M and K0-S have separate fuses and terminal strips.
When replacing a CT24-9 board with a CT24-9-ASO board, it will be necessary to link J1A N/O terminal to J1B C
terminal and to take the J1 C terminal and J2 NC terminal to the machine main contactor control circuit, as the
CT24-9 only has one terminal pair; see Figure 14.
