Timing Mode:

Power is applied to the relay prior to the timing cycle. Upon application of power to the
trigger input terminal the load is energized. When power is removed from the trigger
terminal the time delay cycle is initiated. At the end of the delay time the load is de­energized. Reset is accomplished by reapplying power to the trigger input terminal.

Definition of a part number for the Amperite STB Series Time Delay Relay:
Example:

A: Denotes nominal input voltage. Voltages available: 12V, 24V, 120V & 230V AC;
12V, 24V, 48V & 110V DC. Custom voltages are available.

B: Denotes type of input power required for operation: A = AC - Alternating Current; D
= DC - Direct Current.

C & D: Denotes range of adjustability by using an external resistor or potentiometer,
where C is the minimum timing and D is the maximum timing. Standard timing span is
100:1. For fixed timing units specify a single number.

E: Denotes unit of time delay: S=seconds; M=minutes; H=hours.

F: Denotes Amperite STB Series triggered delay-on-release relay.
