CT2A Datasheet, PDF (1/1 Pages) List of Unclassifed Manufacturers – Electronic timer relay

TIME CUBE 8 and 11-Pin, Time Cube
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.
CT 2A CT 3A
Off delay
The timing starts when S is switched off.
The relay drops out at time (t).
CT 2B CT 3B
Blinker
The relay blinks ON/OFF at time (t) when
switch S is closed. First pulse, ON.
