This timer relay is designed for reliable control in various electrical applications. With a supply voltage of 220 to 240V AC, it fits seamlessly onto DIN rails for easy installation. The device measures 23mm wide, 75mm deep, and 85mm long, making it compact yet powerful. Its primary mode of operation is ON delay, ensuring precise timing functions are met.

• Delivers adjustable time ranges from 0.8 to 60 seconds
• Features a single timer function for straightforward operation
• SPDT contact configuration enables versatile connectivity
• Built to operate in extreme temperatures, -25 °C to +60 °C
• External power supply supports reliable performance under load
• Screw terminal type ensures secure and stable connections

• Used in automation systems to manage operational timings
• Ideal for wye-delta starters ensuring safe switching
• Utilised in electrical installations requiring precise timing control
• Employed in machinery automation for enhanced efficiency

The ON delay function initiates the countdown immediately upon energisation, starting with contact 15-16 closing. After the pre-set time elapses, contact 15-16 opens and a fixed 50 ms lapse begins before contact 15-18 closes, ensuring no short-circuit occurs.

Upon de-energisation, both indicator lights turn off after 250 ms, signalling that the device has reset and is ready for a new cycle, facilitating a smooth transition between operations.

Temperature variations can influence time delay settings, as the device has a drift rate of -0.2% per °C. It's advisable to consider this drift if adjustments are made significantly outside the standard operating temperature range for accuracy.
