Description
Futek USA Industrial Time Delay Relay
Model: SA3PA-B | 24VDC Operating Power | 0–60 Second Adjustable Range
Used Condition
— Authentic industrial automation pull. The analog adjustment dial, structural plastic face casing, and base alignment pin interface have been verified for immediate machinery re-commissioning.
Product Overview
The genuine Futek USA SA3PA-B Time Delay Relay is a rugged, highly reliable timing control module engineered to deliver deterministic automation pacing within harsh factory environments. Powered by a standard 24VDC control loop supply, this analog timer utilizes a smooth-travel front potentiometer knob to select an adjustable delay window spanning from 0 to 60 seconds. It serves as a vital hardware layer for establishing staggered power distributions, safe equipment sequence interlocking, and machinery startup delays across modern and legacy electrical control cabinets alike.

Key Features & Structural Benefits
- Deterministic Timing Circuits: Solid-state timing components ensure repeatable accuracy across continuous cycles, bypassing the variances common in thermal or mechanical switches.
- High-Contrast Analog Faceplate: The clean numeric font layout permits field engineers to verify or update the target delay constraint without connecting external software utilities.
- Robust Base Contact Configuration: Premium pin alignment facilitates tight mechanical friction mapping when seated into standard panel-mount or DIN rail base sockets.
- Tough Thermoplastic Enclosure: Designed to offer durable resistance against local vibration shocks, operational thermal fluctuations, and typical factory floor conditions.
Logistics & Commercial Handling
Secure Impact-Resistant Packaging: To fully isolate the front-mounted adjustment knob, crystal cover, and delicate contact pins from transit damage, this timer relay is packed within structural anti-static cushioning layers and boxed in a rigid outer shipping carton. Fully tracked logistics dispatch is updated immediately upon purchase.
