Industrial 438UP Industrial Solid State Timer Relay

The Artisan 438UP Universal Potentiometer Time Capsule is a solid‑state timer relay that provides a reliable delay‑on‑make control for loads operating from 19–288 V AC or DC. It is designed to be placed in series with the load, remaining non‑conducting for a user‑adjustable interval after power is applied and then energizing the circuit once the timer elapses. Timing is set with an external resistor or potentiometer connected to the center terminals; depending on the variant, the timing range typically spans from 1 to 1000 seconds (and 2 to 2000 seconds on higher‑range versions), with the external timing element ranging up to 10 megohms. The device supports load currents up to 1 A inductive, with inrush currents up to 25 A for 8 milliseconds. Panel‑mount variants exist under the 438UPS designation for control‑panel installations. The 438UP family is UL/cUL listed for safety in common control environments and is commonly used to sequence relays, solenoids, or lamps in applications such as HVAC control, transportation systems, and elevator/escalator equipment where a repeatable, in‑line delay is required.
