The Panasonic LT4H-AC240V is a multi-function digital timer for 100-240V AC, with SPDT delayed contacts rated 5 A resistive at 250 V AC.
Its delay is adjustable from 0.001 s to 999.9 h. Ranges: 9.999 s, 99.99 s, 999.9 s, 9999 s, 99 min 59 s, 999.9 min, 99 h 59 min or 999.9 h (DIP switch). Operation modes: Power ON delay (1), Power ON delay (2), Signal ON delay, Signal OFF delay, Pulse One-shot, Pulse ON delay, Signal Flicker, Totalizing ON delay. Setting: Front keypad; DIP-switch range and mode. Reset: Front reset switch or reset input. Display: 7-segment LCD, red elapsed value, yellow setting value. Memory: EEPROM: keeps the setting and time data through a power loss. Option: Times up or down (DIP switch).
Setting accuracy: ±(0.005% + 50 ms) at power-on start. Supply tolerance: 85 to 110%; 50/60 Hz (AC). Power: 10 VA max. Life: 20,000,000 operations mechanical, 100,000 electrical.
It plugs into an 11 pin socket. Protection: IP66 front panel. Panel cutout: 45 x 45 mm (1.77 x 1.77 in), 1/16 DIN. Dimensions: 48 x 48 x 70.1 mm. It operates from -10 to +55 °C. Approvals: cULus, CE.
