    SECTION 4 - PROGRAMMING GUIDE pickering MODULE ARCHITECTURE The 40-747 series of PXI modules are arrays SPDT relays configured as 16-channel (40-747), dual 8-channel (40- 748) and quad 4-channel tree multiplexers. Energising a particular signal path energises the corresponding relays to create a connection between the common and the required channel terminal.
