TS-203

The TS-203 is an accurate, user-friendly digital time switch designed for daily on/off control of loads via a built-in real-time clock. With support for up to 4 on/off programs per day, LCD display, LED status indicators and a high-capacity switching relay, it is ideal for panel-mounted automation in commercial and industrial applications.

Key Features:

• Real-time clock in 24-hour format with built-in battery backup for reliable time-keeping even during mains interruption. 

• Four programmable operating periods each day (start time + duration), giving flexible scheduled control of loads. 

• Output contact rating: 1 change-over (C/O) relay, rated for 16 A resistive load (250 V AC / 28 V DC).

• Multi-voltage variants available (typically rated for 240 V AC supply) with wide tolerance (-20% to +10%).

• Durable build: switching accuracy ±2 seconds (typical), electrical life ≥ 10⁵ operations under full load.

• Panel-mount friendly footprint (e.g., 72 × 72 × 84 mm for the TS-203 version) and standard cut-out sizes. 

• Manual override facility lets you toggle the output relay for testing or manual control. 

Applications:

• Scheduled automation of lighting, ventilation, pumps, fans, HVAC or other loads in buildings, industrial plants and utilities.

• Panel-mounted control systems where predictable daily switching is required (for example, switching on/off at set times each day).

• Wherever robust, dependable timed switching is needed with minimal operator involvement.
