Motor starting sequences, star-delta changeovers and staged conveyors often need a simple mechanical delay on a contactor rather than a separate electronic timer relay. The Techspan TA2DT4 is a pneumatic on-delay timer block with an adjustable delay listed as 10 to 108 seconds. Control panel builders and maintenance electricians use it to add timed contacts to an existing contactor.
Why panel builders pick it
- Adds an on-delay function directly to a contactor without a separate timer relay or extra DIN space.
- Pneumatic timing needs no separate power supply.
- Adjustable delay range listed as 10-108 seconds.
- Techspan part, stocked in Canada for quick replacement.

Pro tip from the counter
Pneumatic timers drift with temperature and wear, so set the dial, then time the first few cycles with a stopwatch and fine-tune. Before ordering, confirm the timer block fits the contactor frame in your panel; front-mount timer blocks are specific to their contactor family.
Best for: motor start sequencing, star-delta starter timing, conveyor and fan staging, control panel repairs
