The potential multiplication module is used in combination with the 8-channel output terminal 750-530 to provide the 0-V potential for the outputs. This makes the use of additional terminal blocks unnecessary. The potential multiplication module receives the 24-V supply voltage and the 0-V potential via the internal power contacts of an upstream bus terminal. When the bus terminal is engaged, the potentials are then automatically connected through to the downstream terminals via the power contacts. The 0-V potential is provided to all eight CAGE CLAMP® connections for the field level and the 24-V supply is passed on without direct usage.
