Control higher-current or 240VAC loads through an external relay
The DCT24PB does not switch 240VAC directly. Its 1 A / 30 VDC volt-free output can energise the coil of a suitably rated external relay or contactor, which then switches the connected load.- Use the timer output to operate the external relay coil.
- Fit a back-EMF protection diode across a DC relay coil to protect the timer from voltage spikes.
- Applications can include timed fans, lights, heaters, compressors and pump-control circuits.
All 240V wiring must be completed by a licensed electrician.

Common DCT24PB questions
Is the DCT24PB similar to an ISG12 or ISG24 timer?
It provides similar countdown-timer functions, with the timing carried out electronically and operated through dedicated push buttons.
Can the DCT24PB replace a Powerite BCT2 or BCT2S?
It is designed as a direct panel-size replacement in compatible 12V installations. The 44.7 × 44.7 mm front suits the standard 45 mm square panel opening. Confirm terminal wiring and connected load before installation.
What is the maximum countdown time?
Up to 24 hours.
What are the relay contacts rated for?
The volt-free changeover contacts are rated at 1 A at 30 VDC for a resistive load.
Can it switch a high-current or 240VAC load directly?
No. Use a correctly rated external relay or contactor. All mains wiring must be completed by a licensed electrician.
