low voltage products & systems 5.136 accessories description the hrdi series combines an electromechanical relay output with microcontroller timing circuitry. it offers 12 to 230 v operation in five ranges and factory fixed, external, or onboard adjustable time delays with a repeat accuracy of +/-0.5%. the output contact rating allows for direct operation of heavy loads such as compressors, pumps, blower motors, heaters, etc. this series is ideal for oem applications where cost is a factor. operation upon application of input voltage, the time delay begins. the output relay is energized during the time delay. at the end of the time delay, the output de- energizes and remains de-energized until input voltage is removed. reset: removing input voltage resets the time delay and the output. see accessory pages for specifications. hrdigen 10.03.05 30 a spdt n.o. output contacts 12 ... 230 v operation in 5 ranges encapsulated circuitry delays from 100 ms ... 100 m in 5 ranges +/-0.5% repeat timing accuracy fixed, external, or onboard adjustment approvals: interval (single pulse on operate) hrdi power-time time delay relay connection example p/n: function note: a knob, or terminals 4 & 5 are only included on adjustable units. r t t is used when external adjustment is ordered. relay contacts are not isolated. dashed lines are internal connections. hrdi x x x x ? 1 - 12 v dc ? 1 -? a - +/-1% ? 0 - 0.1 ... 10 s ? 2 - 24 v ac ? 2 - blank - +/-5% ? 1 - 1 ... 100 s ? 3 - 24 v dc ? 2 - 10 ... 1000 s ? 4 - 120 v ac ? 3 - ? 3 - 0.1 ... 10 m ? 6 - 230 v ac ? 4 - 1 ... 100 m series input adju stment time tolerance time delay * * if fixed delay is selected, insert delay [ 0.1 ? 1000 ] followed by ( s ) sec. or [ 0.1 ... 100 ] ( m ) min. hrdi421 fixed ? hrdi41a0.5s b mounting bracket p/n: p1023-6 female quick connect p/ns : p1015-64 (awg 14/16) p1015-13 (awg 10/12) quick connect to screw adaptor p/n: p1015-18 external adjust potentiometer p/ns: p1004-95 (fig a) p1004-95-x (fig b) versa-knob p/n: p0700-7 din rail adaptor p/n: p1023-20 a din rail p/ns: 017322005 (steel) c103pm (al) fixed onboard knob external adjust v = voltage l = load r = reset td = time delay interval = undefined time c = common, transfer contact no = normally open l = load ordering table
