The unit converts field sensor variables into high-resolution digital data across 8 independently configurable channels. Interfacing directly with the internal backplane bus, the module processes voltage, current, resistance temperature detector (RTD), and thermocouple inputs while executing analog command signals to final control elements.\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\u003eAIO208\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBachmann\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eAustria\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.30 kg (Typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard M1 Module Dimensions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-30 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eBackplane powered (Standard M1 Bus Load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Count\u003c\/td\u003e\n\u003ctd\u003e8 Configurable Analog Input \/ Output Channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Inputs\u003c\/td\u003e\n\u003ctd\u003e+\/-10 V, +\/-1 V, +\/-100 mV, +\/-10 mV, +\/-20 mA, 0-20 mA, 4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Sensors\u003c\/td\u003e\n\u003ctd\u003ePt100\/Pt1000 (2-, 3-, 4-wire), Thermocouples (J, K, T, N, E, R, S, B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Outputs\u003c\/td\u003e\n\u003ctd\u003e+\/-10 V (max 10 mA), 0(4)-20 mA (max load 600 ohm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput \/ Output Resolution\u003c\/td\u003e\n\u003ctd\u003e16-bit Input (with filter), 14-bit Output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Refresh Cycle\u003c\/td\u003e\n\u003ctd\u003e100 us\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003e500 V Galvanic Isolation\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 Bachmann AIO208 leverages internal backplane bus communication velocity to deliver a fast 100 us refresh cycle across all 8 channels. Combining analog input and output functions on a single board maximizes I\/O density scaling within the M1 rack, eliminating the need for separate dedicated cards. Dynamic digital filters update on a per-channel basis from 4 kHz down to 0.5 Hz to reject electrical noise while preserving fast loop throughput. Solid hardware-level firmware flash compatibility ensures synchronized parameter updates across distributed control structures without interrupting system scan cycles.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does 500 V galvanic isolation protect signal conversion accuracy across mixed channel configurations?\u003c\/p\u003e\n\u003cp\u003eA: Integrated 500 V galvanic isolation isolates the field wiring signals from the internal logic backplane and adjacent channel groups. This barrier suppresses common-mode voltage spikes, preventing ground loop noise from corrupting millivolt-level thermocouple or RTD measurements.\u003c\/p\u003e\n\u003cp\u003eQ: What happens to channel output signals when the system detects an overtemperature or short-circuit fault?\u003c\/p\u003e\n\u003cp\u003eA: The onboard diagnostic engine monitors output circuits continuously. Upon detecting a short circuit or overtemperature condition, the module triggers hardware protection loops, trips localized channel status bits, and forces the affected output into a safe de-energized state.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the AIO208 vertically into the Bachmann M1 base rail slot until the backplane connector locks firmly into place. Secure the top and bottom retaining screws to ensure continuous chassis grounding. Route low-level thermocouple and RTD signal leads through shielded twisted-pair cables, keeping them strictly separated from AC power lines by a minimum clearance of 300 mm.\u003c\/p\u003e\n\u003cp\u003eGround cable shields at a single point on the cabinet entry grounding bar to eliminate ground loop currents. When connecting 3-wire or 4-wire Pt100 sensors, ensure uniform wire resistance across all leads to maintain specified measurement accuracy. Torque terminal block connections to manufacturer specs prior to applying power to the rack.\u003c\/p\u003e","brand":"BACHMANN","offers":[{"title":"Default Title","offer_id":52890603487544,"sku":"AIO208","price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/244.jpg?v=1788256173","url":"https:\/\/www.automodulexpert.com\/products\/aio208-m1-bachmann-automation-system-analog-controller-module","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
