This board is inserted into the yellow plastic frame which holds 1 main board allowing connection to sub PCB’s. The sub PCB’s can include HSSB, RISC CPU, data server and ethernet, FL-NET and device Net B cards amongst others.
Some controls have no sub PCB fitted as the control dependent on the main PCB can control 2 or 4 axis and spindle.
We have these A20B20030270 connector boards in stock. They do fail on occasion. We also have complete control i series from the yellow 1 slot box, through to the main control PCB, plug in boards and the sub cards for various i series controls.
