Sangamo SC4411PRO4 1 Channel 7 Day Digital Time Switch with Bluetooth - Panel Mount

The Sangamo SC4411PRO4 is a digital 7-day time switch with one channel and Bluetooth programming capability via iOS, Android or Windows apps. The unit provides a 16A volt-free changeover contact (SPDT relay output) and stores up to 300 switching events in memory, allowing complex daily, weekly or seasonal schedules to be programmed without requiring mains power to hold the settings.

Designed for panel or surface mounting in commercial, industrial and residential applications, the SC4411PRO4 controls heating systems, lighting circuits, pumps, ventilation fans, and other timed loads up to 16A resistive. The volt-free contact means the unit can switch AC or DC loads and integrates into systems where the control signal is isolated from the power circuit being switched. The Bluetooth programming removes the need for physical buttons on the unit itself once initial setup is complete, and allows schedule adjustments from a phone or tablet within Bluetooth range.

The unit measures 97mm wide by 80mm tall by 62mm deep and mounts directly onto a panel or surface using the integral mounting lugs. For DIN rail installation, accessory 95587 (sold separately) is required. The backlit LCD displays current date, time, day of the week and active channel status, with a 10-year battery reserve maintaining the clock and memory during power outages. The clear polycarbonate front cover protects the display and control buttons from dust and accidental operation.

Product Specification Sheet

Product Manual

What does 'volt-free contact' mean?

The 16A changeover relay output has no voltage on it — it's a simple switch contact (SPDT) that can switch AC or DC loads without being tied to mains voltage. This allows the SC4411PRO4 to control low-voltage systems, motor contactors, or isolated circuits where galvanic separation between control and load is required.

How is the time switch programmed?

Programming is done via the Sangamo Bluetooth app on iOS, Android or Windows devices. Once paired via Bluetooth, switching events can be added, edited or deleted from the app and transferred to the unit's 300-event memory. Manual programming using the four front-panel buttons is also supported.

Can it be mounted on DIN rail?

The SC4411PRO4 ships ready for panel or surface mounting. For DIN rail installation, Sangamo accessory 95587 (sold separately) is required to adapt the unit to 35mm DIN rail.

What happens during a power cut?

The 10-year battery reserve maintains the clock and all stored switching events during mains power outages. When mains power returns, the unit resumes normal operation without needing to be reprogrammed.
