MODULE ARCHITECTURE - 40-125-121
One sub-unit is used to control all the module’s relays as shown below. Enabling a particular bit closes the C to A
signal path.

The 40-125-121 is an array of 24 uncommitted screened SPST relays. In the default state, all signal paths are open.
Energising a particular relay creates a signal path between the C and A terminals. The relay module’s switching
architecture is shown in the default state in the diagram below:
