(50.8 mm) square. its microcontroller timing circuit provides excellent repeat accuracy and stability. encapsulation protects against shock, vibration, and humidity. the krdb series is a cost effective approach for oem applications that require small size, isolation, reliability, and long life. operation operation operation operation operation input voltage must be applied before and during timing. upon closure of the initiate switch, the output relay energizes. the time delay begins when the initiate switch is opened. the output remains energized during timing. at the end of the time delay, the output de-energizes. the output will energize if the initiate switch is closed when input voltage is applied. reset: reset: reset: reset: reset: reclosing the initiate switch during timing resets the time delay. loss of input voltage resets the time delay and output. see accessory pages for specifications. krdbgen 01.12.05 compact time delay relay microcontroller circuitry, +/-0.5% repeat accuracy isolated 10 a spdt output contacts onboard or external adjustment or fixed time delay delays from 100 ms ... 1000 m in 6 ranges input voltages from 12... 120 v in 4 ranges +/-5% factory calibration approvals: delay on break (release) delay on break (release) delay on break (release) delay on break (release) delay on break (release) krdb digi-timer time delay relay connection connection connection connection connection example p/n: example p/n: example p/n: example p/n: example p/n: function function function function function din rail p/ns: 017322005 017322005 017322005 017322005 017322005 (steel) c103pm c103pm c103pm c103pm c103pm (al) din rail adaptor p/n: p1023-20 p1023-20 p1023-20 p1023-20 p1023-20 female quick connect p/ns: p1015-64 p1015-64 p1015-64 p1015-64 p1015-64 (awg 14/16) p1015-13 p1015-13 p1015-13 p1015-13 p1015-13 (awg 10/12) mounting bracket p/n: p1023-6 p1023-6 p1023-6 p1023-6 p1023-6 quick connect to screw adaptor p/n: p1015-18 p1015-18 p1015-18 p1015-18 p1015-18 v = voltage s1 = initiate switch r = reset no = normally open nc = normally closed td = time delay delay on break = undefined time a knob is supplied for adjustable units. the untimed load is optional. relay contacts are isolated. dashed lines are internal connections. series series series series series krdb krdb krdb krdb krdb ? 1 1 1 1 1 - 12 v dc ? 2 2 2 2 2 - 24 v ac/dc ? 4 4 4 4 4 - 120 v ac ? 5 5 5 5 5 - 110 v dc ? 1 1 1 1 1 - fixed ? 2 2 2 2 2 - onboard adjustment ? 3 3 3 3 3 - external adjustment ? 0 0 0 0 0 - 0.1 ... 10 s ? 1 1 1 1 1 - 1 ... 100 s ? 2 2 2 2 2 - 10 ... 1000 s ? 3 3 3 3 3 - 0.1 ... 10 m ? 4 4 4 4 4 - 1 ... 100 m ? 5 5 5 5 5 - 10 ... 1000 m x x x x x x x x x x x x x x x input input input input input time delay time delay time delay time delay time delay * adjustment adjustment adjustment adjustment adjustment * if fixed delay is selected, insert delay [ 0.1 0.1 0.1 0.1 0.1 ? 1000 1000 1000 1000 1000 ] followed by ( s s s s s ) sec. or ( m m m m m ) min. krdb421 krdb421 krdb421 krdb421 krdb421 fixed ? krdb410.5s krdb410.5s krdb410.5s krdb410.5s krdb410.5s or or or or or dering t dering t dering t dering t dering t able able able able able v = voltage s1 = initiate switch c = common, transfer contact no = normally open nc = normally closed utl = untimed load versa-knob p/n: p0700-7 p0700-7 p0700-7 p0700-7 p0700-7 external adjust potentiometer p/ns: p1004-95 p1004-95 p1004-95 p1004-95 p1004-95 (fig a) p1004-95-x p1004-95-x p1004-95-x p1004-95-x p1004-95-x (fig b) a a a a a b b b b b
