It provides two individually isolated changeover relay contacts (N. O.\/N.C.) that support direct switching of distinct AC and DC load voltages without requiring external interposing relays.Designed for distributed I\/O architectures within CompactLogix and ControlLogix systems,the module mounts on a 1734-TB or 1734-TBS wiring base assembly and draws 100 mA from the internal POINTBus backplane at 5 VDC.\u003c\/p\u003e\n\u003ch3\u003eSignal Switching and Electrical Characteristics\u003c\/h3\u003e\n\u003cp\u003eEach isolated output channel features a single common connection:Channel 0 uses Terminal 4 as common (N.O.across 4 and 0,N.C.(across 4 and 2)while Channel 1 uses Terminal 5 as common (N.O.across 5 and 3,N.C.(across 5 and 1).The Form C contacts support a broad load range from 5 to 28.8 VDC up to 240 VAC at a 2 A resistive load,with a minimum contact load of 5 mA per point to ensure reliable contact wiping.Isolation between contact sets is tested at 2500 VDC for 1 second (250 V continuous isolation voltage).\u003c\/p\u003e\n\u003cp\u003eThe module has a maximum signal turn-on and turn-off delay of 10 ms with a mean contact bounce time of 1. 2 ms. Switching frequency is rated at a maximum of 1 operation every 3 seconds (0. 3 Hz at rated load), yielding an electrical contact life of 1, 000, 000 cycles under resistive loads and 100, 000 cycles under inductive loads. Status monitoring is provided by LED indicators for Module Status, Network Status, and channel activity, while a 7-position keyswitch prevents incorrect module insertion into the wiring base.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1734-OX2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Line\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePOINT I\/O (1734)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDigital Contact \/ Relay Output Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUPC\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e612598285884\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutputs\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 Form C (SPDT) Relays, Individually Isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eContact Voltage Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 to 28.8 VDC \/ 5 to 240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 A Continuous per Point (Resistive)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMinimum Contact Load\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 mA per Point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInitial Contact Resistance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30 mΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperate \/ Release Delay\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10 ms Max (OFF to ON \/ ON to OFF)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBounce Time\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.2 ms (Mean)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax Switching Frequency\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 operation per 3 s (0.3 Hz at rated load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eElectrical Contact Life\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1,000,000 cycles (Resistive) \/ 100,000 cycles (Inductive)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePOINTBus Current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100 mA at 5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Dissipation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.5 W Max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThermal Dissipation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.7 BTU\/hr Max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIsolation Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e250 V Continuous (Tested at 2500 VDC for 1 s between contact sets)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible Wiring Bases\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1734-TB, 1734-TBS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eKeyswitch Position\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePosition 7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-20 to 55 degrees C (-4 to 131 degrees F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Humidity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 to 95% (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.06 kg (0.13 lbs) \/ 1.15 oz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e56.1 x 11.9 x 75.4 mm (2.21 x 0.47 x 2.97 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cp\u003eThe 1734-OX2 does not contain internal output fusing. To protect the module's relay contacts and connected load wiring against overcurrent conditions, external fuses must be installed on each output channel, typically using fused terminal block assemblies.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What contact configuration does the 1734-OX2 module provide? A: The module provides two isolated Form C (Single Pole Double Throw) relay contacts, giving both Normally Open (N. O. ) and Normally Closed (N. C. ) connections for each channel.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 1734-OX2 require an external interposing relay when driving mixed-voltage loads? A: No, because each channel is electrically isolated and supports voltages from 5 VDC up to 240 VAC, it can switch loads with different voltage ratings directly without interposing relays.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 1734-OX2 module feature integrated short-circuit protection? A: No, the module lacks internal fuses. External fusing must be provided in series with each output load to protect the contacts from overcurrent.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53162599940376,"sku":"1734-OX2","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1734-OW2_Cocoai_ab35c563-5687-48f2-bb19-5ac7fb0ea6fd.jpg?v=1793933906","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1734-ox2-point-i-o-2-channel-relay-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
