MODULE ARCHITECTURE - 40-145 NORMALLY CLOSED VERSIONS
One sub-unit is used to control all the module’s relays as shown below. Enabling a particular bit disconnects the C
to B signal path.
40-145-001-NC
(50 x SPST)
The 40-145-001/101/201-NC are arrays of 50, 75 or 100 uncommitted SPST relays. In the default state, all signal
paths are connected between the C and the corresponding B terminals, energising a particular relay disconnects
the signal path The relay module’s switching architectures are shown in their default state in the diagram below:
