Timing Mode:
Delay on operate timing cycle begins upon application of input power. The relay contacts
transfer at the end of the delay period and will remain transferred until input voltage is
removed. Reset occurs when input voltage is removed

Ordering Information:
Definition of a part number for the Amperite SWDC Series Time Delay Relay:
Example:
A: Denotes nominal input voltage. Standard voltages are 12V, 24V and 120V AC; 12V,
24V, 48V and 110V DC. Custom Voltages are available.
B: Denotes type of input current required for operation:
A = AC - Alternate Current
D = DC - Direct Current
C&D: Denotes timing range of adjustability in seconds, minutes, or hours.
E: Denotes unit of time delay: S = seconds; M = minutes; H = hours.
F: Denotes form of termination: Leave blank for standard octal plug-in; Enter "L" if
optional spade terminals are required (Diagrams B & D).
G: Denotes use of solid state digital circuitry of SWDC Series.
