The 3-1423164-5 is an industrial on-delay electropneumatic timing relay, part of the AGASTAT 7000 series. It operates with a 120VAC, 60Hz coil and features a linearly adjustable timing range from 1.5 to 15 seconds, set via a high-resolution dial. Upon energization, the relay begins its preset delay period, after which its 2PDT snap-action contacts transfer the load. The unit is constructed with a modular assembly of a timing head, coil, and switch block, allowing for field-replaceable switches. Its inherent transient immunity and robust design make it suitable for reliable sequencing and programming in severe industrial control applications.
