The Discrete Input and Output (Discrete I/O) is a 24 Vdc function connected using a 28-pin terminal block (BMXFTB28x0). It is a positive logic function where the 8 input channels receive current from the sensors (sink) and the 12 output channels provide current to the pre-actuators (source).
The Discrete I/O function is available on the following PLC:
BMK C80 20301
BMK C80 30311
There are two types of 28-pin terminal blocks:
BMX FTB 2820 spring terminal blocks
BMX FTB 2800 caged terminal blocks
