Ordering Information:
Definition of a part number for the Amperite ST1A 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 ST1A Series solid state, delay-on-make timer.
