Connection Of The Expansion Modules To The Main Board - Master 1120.30 Manual For Installation And Use

9. CONNECTION OF THE EXPANSION MODULES TO THE MAIN BOARD

Two types of expansion modules are available, modules for
24V═ (dc) motors and modules for 230V~ (ac) motors.
Each module controls two motors separately.
Example:
I purchase a KL4 station that includes two 24V═ (dc) modules, and I want to add an
additional 24V═ (dc) module. So I have to switch the 100W power supply unit of the
KL4 station with a 150W power supply unit.
The same KL4 station, with the addition of a 230V~ (ac) module, does not require
any modifications of the power supply unit.
The 230V~ (ac) are powered directly from the mains
network; in this case it's not necessary to check the available
power of the power supply unit.
The 24V═ (dc) modules and the 230V~ (ac) modules can
be positioned in the appropriate seats provided on the
main board, regardless of the type of module.
Caution.
The outputs of the modules of the 230V~ (ac) motors are inverted with
respect to the modules of the 24V═ (dc) motors.
If 24V═ (dc) modules are used, it is important that you check
the power supply unit included in the supply; each 24V═ (dc)
module requires an additional power of about 50W from the
power supply unit.
It is advisable to check that each module contains a fuse for
protection of the associated pair of motors.
For insertion of the modules in the seats provided, just insert
the pin connectors in the appropriate seats, ensuring that the
terminals face the exterior of the main board edge, see
image to the side.
