SECTION 4 - PROGRAMMING GUIDE
MODULE ARCHITECTURE - 40-146
One sub-unit is used to control all the module’s relays as shown below. Enabling a particular bit closes both C to A
signal paths of the corresponding channel.
40-146-002 (25 x DPST)
The 40-146 is an array of 25 or 50 uncommitted DPST relays. In the default state, all signal paths are open.
Energising a particular relay creates a signal path between the C and A terminals of both poles of the corresponding
channel. The relay module’s switching architectures are shown in their default state in the diagram below:
