The 4-1437459-6 is an AGASTAT 7000 series industrial electropneumatic timing relay, model 7012AC, designed for on-delay applications. It operates with a 120V 60Hz coil and features a linearly adjustable timing range from 1.5 to 15 seconds, set via a high-resolution adjustment knob. This relay provides a 2PDT snap-action switch output with a repeat accuracy of ±5% and a reset time of 50 milliseconds. The modular construction, inherent transient immunity, and front-facing screw terminals make it a reliable and flexible solution for sequencing and programming equipment in demanding industrial environments.
