MODULE ARCHITECTURE 40-510
The 40-510-021 is an array of 48 single pole relays, and the 40-510-022 an array of 48 double pole relays. In the
default state all relays are open circuit. Energising a particular relay creates a signal path between its C and A
terminals. The 40-510-021 module's switching architecture is shown in its default state in the diagram below:
One sub-unit is used to control all the module's relays as shown below. Enabling a particular bit closes the contacts
of that crosspoint and creates a signal path. For 2-pole versions, both poles are closed simultaneously.
