The hardware assembly monitors 16 discrete input channels, receiving typical 24 VDC voltage signals from field contact closures, limit switches, and auxiliary relays. Featuring galvanically isolated channel banks and user-defined fail-safe state execution upon communication loss, the module transmits real-time binary telemetry over the backplane to the central CPU.\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\u003e900G02-0203\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.3 kg (9.0 oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e5.1 cm x 15.2 cm x 15.2 cm (2.0 in x 6.0 in x 6.0 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C (32 to 140 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eBackplane powered via HC900 chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Channels\u003c\/td\u003e\n\u003ctd\u003e16 discrete input channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGalvanic Isolation\u003c\/td\u003e\n\u003ctd\u003eGalvanically isolated in 2 groups of 8 channels to chassis ground\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFail-Safe Execution\u003c\/td\u003e\n\u003ctd\u003eUser-defined state on backplane communication timeout\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStatus Indicators\u003c\/td\u003e\n\u003ctd\u003ePOWER, STATUS, FAULT, TX\/RX status LEDs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eRack-mounted in ControlEdge HC900 I\/O chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel-to-Channel Isolation \u0026amp; DCS Field Interfacing\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eHoneywell 900G02-0203\u003c\/strong\u003e digital input card incorporates robust galvanic isolation divided into two independent 8-channel groups. This internal electrical barrier isolates field-side ground potential differences from the sensitive backplane logic circuits, protecting the system against common-mode voltage transients. Suppressing ground loops across incoming discrete lines prevents signal degradation on adjacent analog input channels processing sensitive 4-20 mA HART loop protocol loops within the same I\/O rack.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the 900G02-0203 input module behave if communication with the HC900 CPU is lost?\u003c\/p\u003e\n\u003cp\u003eA: The module executes a user-defined fail-safe state configuration, maintaining assigned discrete logic default states until backplane bus communication is re-established.\u003c\/p\u003e\n\u003cp\u003eQ: Are the 16 input channels on the 900G02-0203 individually isolated from each other?\u003c\/p\u003e\n\u003cp\u003eA: No, the 16 discrete channels are divided into two galvanically isolated groups of 8 channels each, sharing common return terminals within each group.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSeat the 900G02-0203 module firmly into its designated slot within the ControlEdge HC900 rack until the retention latches lock securely.\u003c\/li\u003e\n\u003cli\u003eRoute field input wiring through dedicated wire ducts, separating 24 VDC discrete signal lines from high-voltage AC power conductors.\u003c\/li\u003e\n\u003cli\u003eVerify field terminal power source voltage before applying power to ensure incoming voltage matches the 24 VDC nominal rating.\u003c\/li\u003e\n\u003cli\u003eConnect cable shields to the system grounding bar at one end only to prevent secondary ground loop path formation.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53532179661109,"sku":"900G02-0203","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/900H02-0202_de8d0a01-d389-4c46-81f3-720a106eb1ff.png?v=1789107408","url":"https:\/\/www.5gplc.com\/products\/900g02-0203-honeywell-controledge-hc900-digital-input-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
