DC10 Series
… Solid state CMOS digital circuitry
TDR
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 DC10 Series Time Delay Relay.
Example:
A: Denotes nominal input voltage. Voltages available: 12, 24 & 120V AC; 12, 14, 48, &
110V DC, Custom voltages are available.
B: Denotes type of input current required for operation:
A = AC - Alternating Current, D = DC - Direct Current
C: Denotes contact form: P= DPDT - 2 form C.
D & E: Denotes range of knob adjustability for timing (in seconds, minutes or hours)
where:
D= Minimum time delay. E= Maximum time delay for adjustable TDR’S.
Note:
1.) Ranges available: See standard timing ranges above. Custom timing is available.
2.) Both values (D & E) can be replaced by a single value for a factory preset time delay
in seconds, minutes or hours from 0.1 secs. through 1000 hours.
F: Denotes use of seconds, minutes or hours in timing value(s), S = seconds, M =
minutes, H = hours.
G: Enter "L" if optional 11-pin spade terminals are required (Diagram D). Contact us for
dimensional differences.
H: Denotes use of solid state digital circuitry of DC10 Series.
