The Discrete I/O function is fitted with a removable 28-pin terminal block (BMXFTB28x0) for the connection of 8 input channels and 12 output channels.
The following diagram shows the circuit of a direct current input (positive logic).
The following diagram shows the circuit of a direct current output (positive logic).
The following diagram shows the connection of the function to the sensors and pre-actuators.
power supply:
24 Vdc
input fuse:
fast blow fuse of 0.5 A
output fuse:
fast blow fuse of 12 A
pre-act:
pre-actuator
