The Eaton T6527-50-03-00 is a state‑of‑the‑art electronic time delay relay designed to meet the demanding requirements of industrial automation. It combines a wide supply voltage range (24‑240 VAC/DC) with 10 selectable timing functions and 8 timing ranges, providing maximum flexibility for applications such as motor control, lighting, HVAC, and process control. The relay plugs into a standard 8‑pin octal socket, making it easy to install or replace without rewiring.

The T6527-50-03-00 features a rotary switch or DIP switches (depending on version) to select the desired timing function. Common functions include:
On‑delay (A): Output energizes after a preset time after input voltage is applied.
Off‑delay (B): Output de‑energizes after a preset time after input is removed.
Interval (C): Output energizes for the set time when triggered.
Flashing (E/F): Output cycles on and off continuously.
One‑shot (D): Output produces a single pulse of set duration when triggered.
Motor star‑delta transition timing
Lighting and heating control sequences
Conveyor belt delay before reversal
Pump alternating control
Periodic maintenance reminders
Process industry timing loops
Built with high‑quality components, the timer offers long‑term stability and immunity to electrical noise. It meets IEC 61812‑1, UL 508, and CSA C22.2 No. 14 standards, and is CE marked. The wide operating temperature range makes it suitable for both panel mounting and outdoor enclosures with proper protection.
The Eaton T6527-50-03-00 time relay is a versatile and reliable component for any control system requiring precise timing functions.
