The modules CT 2 and CT 3 are electronic
timers that are designed to be inserted
beween a standard plug-in relay and its
socket, enabling the relay to be operated
as a timer relay.
The CT modules are able to accept any
standard 8 or 11-Pin RELECO series C2
or C3 as well as those from any other
supplier.
The relay coil voltage must be in the range
shown for each model.
