The C-7355 Electromechanical Series of 7-Day Time Clocks
provides an economical control solution for automatic
On/Off switching of equipment.  Electromechanical time
clocks are available in the following types:  C-7355-7 (1
channel with a synchronous drive motor) and C-7355-8 (1
channel with quartz stabilized movement and battery
reserve).

The C-7355 Electromechanical Series uses heavy duty
single-pole/double-throw (SPDT) contacts (rated 21 amps
at 240 VAC resistive) to switch line voltage loads.  Up to 12
two-hour On/Off events per day can be programmed.
