MODULE ARCHITECTURE 40-290-021
Two sub-units (one for each Chain) are used to control the module’s relays as shown below. Enabling a particular
bit closes the C to A signal path of that relay.

The 40-290-021 Module utilises 32 SPST relays. In the default state, all relay signal paths are open circuit and all
resistors are linked in the chains. Energising a particular relay creates a signal path between the C and A terminals
of the relay and short circuits the corresponding resistor. The relay module’s switching architecture is shown in its
default state in the diagram below:
