It provides one normally-open and one normally-closed contact (1NO+1NC) with an adjustable off delay from 10 to 180 seconds, meaning the NC contact holds its state for that set period after the coil de-energises before dropping out. Rated operational current is 6 A at 120 V AC-15 and 0.55 A at 125 V DC-13, with a conventional free-air thermal current of 10 A at 60 °C. Insulation voltage is 690 V per IEC 60947-5-1, 600 V per UL and CSA equivalents. Faston terminals make for quick wiring on the bench or during panel assembly.
The off-delay range of 10 to 180 seconds covers most sequencing and anti-overlap timing needs in motor starter circuits — fan coast-down delays, pump-off timers, or interlock release after a stop command. The 1.5 ms non-overlap time on both energisation and de-energisation ensures the NC and NO contacts never bridge simultaneously, which is critical for safety interlock circuits that must break before make. Mechanical durability is 5 million cycles — a solid figure for a timer block that sees regular cycling in HVAC or conveyor applications. Minimum switching requirements of 5 mA and 17 V mean this block can handle dry-contact PLC inputs without wiper-burn issues — useful when the timer feeds a digital input card rather than a power circuit.
