The Phoenix ETD-BL-1T-230-PT Timer Relay (Part No: 2905814) delivers high-performance switching with long operational life, offering a mechanical endurance of up to 15 million cycles and an electrical service life of 1×10⁵ cycles under 2000 VA resistive loads. This timer relay supports a flexible input voltage range of 24 V AC/DC to 240 V AC/DC (±15%) and is built to work across diverse frequency ranges from 48 to 63 Hz. It offers a time setting range from 50 milliseconds to 1 hour with five adjustable ranges, a basic accuracy of ±1%, and a repeat accuracy of ≤ 0.5% ±5 ms, ensuring precise control across repetitive operations. The recovery time of 100 ms ensures fast cycle resets, while the maximum switching voltage of 250 V AC makes it suitable for a wide array of relay-controlled circuits. Electrical safety is enhanced with a 4 kV test voltage between relay winding and contact, and a 5 A fast-blow output fuse. Its Push-in connection system supports rigid conductor sizes from 0.14 mm² to 2.5 mm² with an 8 mm stripping length, streamlining installation. The built-in green LED status indicator and IP40 housing protection offer clear diagnostics and moderate protection in standard panel environments.
The ETD-BL-1T-230-PT is ideal for electrical engineers managing delay-based operations like fan shutoff delay, batch process sequencing, and power-on startup delays in machinery and HVAC control systems. It is widely adopted in industries where compact, durable timing relays are needed to fit within tight panel spaces without compromising performance. Junior and senior maintenance engineers alike value the intuitive configuration and clear LED status indication. It also serves as a practical learning tool for engineering students studying real-time control logic. With an operating temperature range from -25°C to +55°C, this relay performs reliably in Indian manufacturing environments prone to temperature fluctuations and voltage instability.
