Timing Mode:
Input voltage must be applied continuously to operate the internal relay. Relay contacts
transfer when the trigger input terminal is activated. The timing cycle begins when the
trigger input terminal is deactivated. When the timing cycle is completed the relay will
de-energize. The timing cycle may be reset to zero during the timing cycle by
reactivating the trigger input terminal.

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, 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 (Diagrams B & D).
H: Denotes use of solid state digital circuitry of DCR10 Series.
