This 16-point digital interface card receives binary input signals from field contact switches, proximity sensors, and limit switches, applying a 20 ms input filter delay to suppress contact bounce before transferring bit states across the optical isolation barrier to the central control processor.\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\u003eA03B-0819-C104\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Designation\u003c\/td\u003e\n\u003ctd\u003eAID16D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE Fanuc \/ Fanuc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.66 lbs (0.30 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Fanuc I\/O Model A modular housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Density\u003c\/td\u003e\n\u003ctd\u003e16 discrete input points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Input Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC (+10% \/ -15%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResponse Time\u003c\/td\u003e\n\u003ctd\u003e20 ms input filter delay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to 70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eLogic side powered via backplane bus \/ 24 VDC field side\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 \u0026amp; I\/O Density Scaling\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eA03B-0819-C104\u003c\/strong\u003e card interfaces with the host rack backplane to maintain high backplane bus communication velocity across all active I\/O scan cycles. Optimized for flexible I\/O density scaling, multiple 16-point AID16D modules can be arrayed on the backplane without degrading master cyclic processing times. Verify system firmware flash compatibility across the interface unit during module replacement to ensure correct address mapping and eliminate bus transmission latency across distributed Fanuc I\/O segments.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the A03B-0819-C104 module be removed or inserted into the backplane while the system power is on?\u003c\/p\u003e\n\u003cp\u003eA: No. Hot-swapping the module while backplane logic power or field 24 VDC is present will damage onboard optocouplers and trigger immediate system bus parity errors on the host CNC.\u003c\/p\u003e\n\u003cp\u003eQ: What effect does the integrated 20 ms response delay have on high-speed input signals?\u003c\/p\u003e\n\u003cp\u003eA: The hardware 20 ms filter suppresses high-frequency contact chatter and mechanical switch bounce; however, signals with pulse durations shorter than 20 ms will be filtered out and will not be registered by the input image table.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePower Disconnection: Isolate main 24 VDC power supplies and lock out system control power before connecting field wiring or seating the module into the I\/O base.\u003c\/li\u003e\n\u003cli\u003eGrounding and Shielding: Connect the mounting chassis frame directly to the main enclosure earth bus bar using a low-impedance ground braid to maintain high-frequency noise immunity.\u003c\/li\u003e\n\u003cli\u003eCable Routing: Route 24 VDC field input wiring in separate conduits away from high-voltage AC lines, spindle drive cables, and relay coil power leads to prevent induced transient noise on input channels.\u003c\/li\u003e\n\u003cli\u003eFastener Engagement: Secure the module assembly to the mounting sub-panel using M4 hardware torqued to 1.5 Nm, ensuring at least 5 full threads of engagement into the sub-panel.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"GE","offers":[{"title":"Default Title","offer_id":50524834103411,"sku":"A03B-0819-C104","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-09-24_15-49-40_Cocoai_6e7f0e2a-eb1b-4d09-a793-f96de8f9ecf6.jpg?v=1790237414","url":"https:\/\/www.dcssupplier.com\/products\/ge-fanuc-a03b-0819-c104-digital-input-module","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
