Description
The SHT-1/2/UNI is a 2-channel digital time switch clock designed to control appliances such as heating, pumps, ventilation, and lighting based on real time. Each of its two output channels can be programmed and adjusted individually, giving it the flexibility to run two independent time-based circuits from a single DIN-rail device. It supports daily, weekly, monthly, and yearly programming, with switching modes of automatic (per program), permanently manual, or random — useful for security lighting simulation.
The device is powered from a universal AC/DC 12–240 V supply, making it adaptable to a wide range of control panel and installation voltages without needing a separate model. It offers 100 programmable memory places, a backlit LCD display with a clear bargraph indication for each channel, and a sealable transparent front cover to protect settings from tampering. A built-in battery backs up the real-time clock and stored programs for up to 3 years during power loss, and the clock automatically adjusts for summer/winter time changes. Cyclic and pulse output modes (1–99 s) are also available for applications like staircase lighting or intermittent equipment cycling.
