The Discrete I/O (8 Input 8 Output) function is fitted with a removable 20-pin terminal block (BMXFTB20x0) for the connection of eight input channels and eight 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 6.3 A
pre-act:
pre-actuator
