4.9 Applications of HCU
4.9.1 SLOT Expansion
■
Di󶍽erent function modules are available in the HCU application. The function
modules are installed directly in the SLOT slots of the HCU.
■
The HCU only has three SLOT slots. When more modules are needed, install HOFM
and HESD expansion modules. Each HESD can connect to one function module.
