01FENCE & GATE ACCESSORIES
Precision Timing for Automated Systems
A compact black module that brings order to automated routines, this controller sits quietly within your system, managing intervals with digital precision. Its dual LED display offers immediate visual feedback, making complex timing sequences feel intuitive rather than technical.
Designed for engineers and hobbyists alike, the T3231 handles both single delays and infinite cycles. It suits applications where exact timing is critical, from gate openers to industrial machinery, ensuring every action occurs exactly when intended.


02DESIGN
Compact Embedded Form Factor
Housed in durable ABS plastic, the unit measures 77 by 39.3 millimetres, allowing it to fit neatly into standard control panels or enclosures. The black finish blends seamlessly into most technical environments, while the flat profile ensures it does not protrude awkwardly from the mounting surface.

04FUNCTION
Versatile Timing Modes
The controller supports multiple operational patterns, including single time delays and infinite cycle on-off sequences. With a timing range starting at one second and extending to 999 hours, it accommodates everything from rapid pulses to long-duration hold periods, adapting to diverse automation needs.
RELIABILITY
Power Failure Saving Feature
In the event of a temporary power interruption, the device retains its programmed settings, preventing the need for recalibration upon restart. This memory function ensures continuity in automated systems, maintaining schedule integrity even after brief electrical disruptions.
