x ? 1 - fixed low voltage products & systems 5.16 accessories description the tdu and ksdu series are encapsulated solid state delay on make timers that combine digital timing circuitry with universal voltage operation. the tdu offers dip switch adjustment allowing accurate selection of the time delay over the full time delay range. the ksdu is factory fixed from 0.1 s to 10,230 s and does not include the dip switch. these series are excellent choices for process control systems and oem equipment. operation upon application of input voltage, the time delay begins. the output is de-energized before and during the time delay. at the end of the time delay, the output energizes and remains energized until input voltage is removed. reset: removing input voltage resets the time delay and output. see accessory pages for specifications. tdksdub1 06.09.04 2 universal voltage ranges from 24 ... 240 v ac/dc digital integrated circuitry switch selectable delays from 0.1 s ... 2.8 h in 3 ranges or factory fixed +/-0.5% repeat accuracy 1 a steady - 10 a inrush totally solid state and encapsulated approvals: delay on make (operate) tdu, ksdu digi-set timing modules connection example p/n: function din rail p/ns: 017322005 (steel) din rail adaptor p/n: p1023-20 female quick connect p/n: p1015-64 (awg 14/16) mounting bracket p/n: p1023-6 quick connect to screw adaptor p/n: p1015-18 c103pm (al) v = voltage r = reset td = time delay l = load = undefined time delay on make dashed lines are internal connections. load may be connected to terminal 3 or 1. tdu has dip switch adjustment; ksdu is fixed. 24 ... 120 ac/dc 100 ... 240 ac/dc 24 ... 120 ac/dc 100 ... 240 ac/dc 24 ... 120 ac/dc 100 ... 240 ac/dc tdul3000a tdul3001a tdu3000a tdu3001a tduh3000a TDUH3001A 0.1 ... 102.3 0.1 ... 102.3 1 ... 1023 1 ... 1023 10 ... 10230 10 ... 10230 time range - seconds part number input voltage range x ?specify fixed delay in seconds 0.1 ... 10230 x ? 8 - 24 ... 120 v ac/dc ? 9 - 100 ... 240 v ac/dc series input voltage range type time delay (seconds) ksdu ksdu81300, ksdu910.1 tdu series ordering table
