SECTION 4 - PROGRAMMING GUIDE
MODULE ARCHITECTURE - 40-148
One sub-unit is used to control all the module’s relays as shown below. Enabling a particular bit opens the C to B
signal path and closes the C to A signal path.
40-148-001 (32 x SPDT)
The 40-148 is an array of 32, 48 or 64 uncommitted changeover relays. In the default state, all signal paths are
between the C terminal and the corresponding B terminal. Energising a particular relay disconnects the B terminal
and creates a signal path between the C and A terminals. The relay module’s switching architectures are shown in
their default state in the diagram below:
