CI Series
… Solid state analog circuitry
TDR
Timing Mode:
Relay contacts transfer and timing cycle begins, upon application of power. At the end of
the timing cycle, the relay contacts return to the De-Energized position. Reset occurs
upon removal of the input power.
… One-shot timing mode (interval on)
… DPDT (2 form C) isolated 10 ampere relay
contacts
… Timing selection: Knob adjustable or Fixed
… Numerous models timing from 0.1 secs. to 480
secs.
… UL File #E96739 (M)
… CSA File #LR62586-3

Definition of a part number for the Amperite CI Series Time Delay Relay.
Example:
A: Denotes nominal input voltage. Voltages available: 12, 24, & 120V AC; 12, 24, 48 &
110V DC. Custom voltages are available.
B: Denotes type of input current required for operation. A=AC - Alternating current;
Page 4
D=DC - Direct current.
C: Denotes contact form: P= DPDT - 2 form C.
D & E: Denotes range of knob adjustability for timing (in seconds) where:
D= Minimum time delay.
E= Maximum time delay for adjustable TDR'S.
Note: 1.) Ranges available: 0.1 - 60, 60 - 120, 120 - 180, 180 - 240, 240 - 300 & 300 480 secs. Custom Timing is available.
2.) Both values (D & E) can be replaced by a single value for a factory preset time delay
in seconds from 0.1 through 480 secs.
F: Enter "L" if optional 11-pin spade terminals are required (Dia. B &D).
G: Denotes use of solid state analog circuitry of CI Series.
