Amperite CIR Series TDR Data Sheet

CIR Series
… Solid state analog circuitry
TDR
Timing Mode:
Input voltage must be applied continuously to operate the internal relay. The relay energizes and timing begins when the external switch is closed. At the end of the time delay period the relay will de-energize. Reset is accomplished by opening and re-closing the control switch.

Definition of a part number for the Amperite CIR 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 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 CIR Series.
