Featuring 16 groupwise isolated channels with input impedance rated at 9.6 k-ohms, the 0.22 kg module evaluates logical \"0\" between -60 V and +10 V and logical \"1\" between 30 V and 60 V. The unit draws up to 120 mA from the +5 V Modulebus and supports field cable distances up to 600 meters.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\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\u003eModel\u003c\/td\u003e\n\u003ctd\u003eDI831 (3BSE013212R1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase Model\u003c\/td\u003e\n\u003ctd\u003eDI831\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eSweden\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.22 kg (0.48 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e45 mm x 119 mm x 102 mm (W x H x D)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 deg C to +55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e3.2 W typical power dissipation (120 mA max at +5 V Modulebus)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e16 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Type\u003c\/td\u003e\n\u003ctd\u003e48 VDC current sinking\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range \"0\"\u003c\/td\u003e\n\u003ctd\u003e-60 V to +10 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range \"1\"\u003c\/td\u003e\n\u003ctd\u003e30 V to 60 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e9.6 k-ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEvent Recording Accuracy\u003c\/td\u003e\n\u003ctd\u003e-0.3 ms to +0.7 ms (0.4 ms resolution)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDielectric Test Voltage\u003c\/td\u003e\n\u003ctd\u003e500 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStatus Diagnostics\u003c\/td\u003e\n\u003ctd\u003eFront LEDs: Fault, Run, Warning, Channels 1-16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity and Deterministic Networks\u003c\/h3\u003e\n\u003cp\u003eThe 16-channel discrete module interfaces directly over the local Modulebus to maintain high communication velocity during deterministic scan cycles. Integrated sequence of events logic captures state transitions at 0.4 ms resolution, sending time-stamped status frames across the backplane bus to ensure accurate event ordering in centralized alarm buffers. Controller firmware flash compatibility allows configurable digital filter times from 0 to 100 ms to be loaded online without interrupting execution on parallel I\/O channels.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What sequence of events (SOE) resolution and accuracy does the DI831 module provide?\u003c\/p\u003e\n\u003cp\u003eA: The module records field event transitions with a resolution of 0.4 ms and an overall timestamping accuracy ranging from -0.3 ms to +0.7 ms.\u003c\/p\u003e\n\u003cp\u003eQ: How is galvanic isolation structured across the 16 digital input channels?\u003c\/p\u003e\n\u003cp\u003eA: Channels are groupwise isolated from ground with a rated insulation voltage of 50 V and tested to a dielectric withstand voltage of 500 VAC.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSnap the module onto the corresponding S800 Module Termination Unit (MTU) until the mechanical locking tabs engage.\u003c\/li\u003e\n\u003cli\u003eEnsure all 48 VDC field wiring runs remain within the maximum cable length limit of 600 meters.\u003c\/li\u003e\n\u003cli\u003eConnect shielded field wiring directly to the MTU grounding bar to minimize high-frequency electromagnetic noise.\u003c\/li\u003e\n\u003cli\u003eVerify proper bus clock synchronization across the rack to prevent \"Time synchronization missing\" diagnostic faults.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53227495162165,"sku":"DI831 3BSE013212R1","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/DI831.png?v=1785390920","url":"https:\/\/www.5gplc.com\/products\/di831-3bse013212r1-abb-digital-input-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
