Artisan Controls Corporation Solid State Timer, 30Sec, 12Vac/dc; Relay Mounting Artisan Controls 438A-12-1

The Model 438A-12-1 is an adjustable delay-on-make solid state timer designed to energize a load after a preset delay, operating on 12V AC/DC. It features .250 quick connect terminals and is constructed as an encapsulated module. The timing range for the -1 range is 0.1 to 30 seconds, set by an external resistor. The output supports load currents from 10mA to 1A with inrush capability to 25A for 8ms, and the output switch has a 4V drop when ON and 3mA leakage when OFF. Timing accuracy is within ±15% of the set point, with less than 6% variation over full temperature and voltage range. Repeatability is ±1% at stabilized conditions, and recycle requires removal of voltage for at least 50ms. The device is rated for operation between -20°C and +85°C and includes transient protection up to 6000V. Agency recognitions include UL File #E47858 and ATNZ2/ATNZ8, NKCR2/NKCR8.
