The T3231 Programmable Time Control Controller is a digital time delay device with a single channel relay output. It is designed for precise timed control of electrical loads and supports auto and manual trigger operation, along with an external trigger interface. Operating from standard mains, it handles voltages in the 110220VAC range and supports up to 2200W of load. Multicolor indicators provide clear status feedback for quick, ataglance monitoring. Key benefits Precise timed control: digital time delay capabilities allow accurate scheduling and delay of connected devices. Flexible triggering: choose Auto or Manual trigger operation to fit your process, with an external trigger interface for integration with other control systems. Simple relay output: 1channel relay switch provides a straightforward on/off control for a wide range of loads. Energy and asset protection: automates equipment start/stop to optimize energy usage and extend equipment life. Clear status visibility: multicolor indicators make it easy to see current state and mode at a glance. Mains compatibility: designed to operate from 110 to 220VAC with a maximum load of 2200W. Key attributes Functionality: programmable time delay with digital control; 1channel relay output; active output configuration. Compatibility: supports standard 110220VAC supply; suitable for devices up to 2200W. Trigger options: Auto trigger mode, Manual trigger mode, and external trigger interface for external control signals. Output: 1way relay switch (single channel) for controlled devices. Indicators: multicolor status indicators for ataglance operation feedback. Power and load characteristics: rated for 110220VAC input; maximum load up to 2200W. Design emphasis: compact digital timer solution with straightforward operation and clear visual cues. Use cases Case 1: Lighting control for signage or display areas Schedule automatic on/off times to align with business hours or show cycles, reducing energy use and extending lamp life while maintaining consistent illumination. Case 2: Delayed equipment start for safety or process sequencing Implement a controlled delay before starting fans, pumps, or other equipment after a trigger, ensuring safe startup and smoother process sequences. Case 3: Sensor or controllertriggered automation Connect an external trigger from a PLC, sensor, or other controller to initiate a timed on or off cycle, enabling coordinated automation across systems.
