The module processes 8 differential channels converting millivolt level inputs spanning -30 mV to +75 mV into digital process variables. Channel 8 dynamically configures for cold junction compensation via a 4-wire Pt100 RTD sensor. The internal A\/D conversion circuit utilizes a 15-bit resolution profile with groupwise isolation rated at 50 V continuous insulation to prevent ground loop noise injection.\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\u003eAI835A\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\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.22 kg\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\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\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e1.6 W max (Modulebus: 75 mA at 5 VDC, 50 mA at 24 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Count\u003c\/td\u003e\n\u003ctd\u003e8 differential channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Types\u003c\/td\u003e\n\u003ctd\u003eTC Types B, C, D, E, J, K, L, N, R, S, T, U and -30 to +75 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eA\/D Resolution\u003c\/td\u003e\n\u003ctd\u003e15 bits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 1 M ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCold Junction Compensation\u003c\/td\u003e\n\u003ctd\u003eChannel 8 configurable via 4-wire Pt100 RTD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eGroupwise isolated from ground (50 V rated, 500 VAC dielectric test)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Mode Rejection Ratio\u003c\/td\u003e\n\u003ctd\u003e120 dB at 50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Termination Units\u003c\/td\u003e\n\u003ctd\u003eTU810, TU812, TU814, TU818, TU830, TU833\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication and Channel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe AI835A interfaces with the AC 800M controller rack via the high-speed S800 Modulebus backplane. Digital data serialization travels through the backplane bus, driving real-time diagnostic reporting for wire-break faults, out-of-range signal values, and internal hardware faults. Hardware-level channel isolation isolates the field wiring signals from the internal Modulebus digital processing logic. This internal galvanic barrier provides 500 VAC dielectric withstand capacity, attenuating common-mode voltage spikes and maintaining signal integrity across noisy industrial field environments without degrading the 120 dB common-mode rejection performance.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can Channel 8 be used as a standard input if cold junction compensation is handled externally?\u003c\/p\u003e\n\u003cp\u003eA: Yes. Channel 8 operates as a standard thermocouple or millivolt differential input channel when external cold junction compensation or linear millivolt processing is specified in the system configuration software.\u003c\/p\u003e\n\u003cp\u003eQ: What happens to the process output when a wire-break condition is detected on an active thermocouple channel?\u003c\/p\u003e\n\u003cp\u003eA: The module executes wire-break detection circuitry on the affected channel and sets the corresponding status bit on the Modulebus frame. The controller application software reads this fault state to trigger down-scale or up-scale safety values as defined by system logic.\u003c\/p\u003e\n\u003cp\u003eQ: Is hot-swapping permitted for this module during active system operation?\u003c\/p\u003e\n\u003cp\u003eA: Hot-swapping depends entirely on the base Module Termination Unit (MTU) used. When installed on double-bed MTUs such as the TU830 or TU833, the module can be safely removed and replaced under power without interrupting field cabling or adjacent I\/O channel communication.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eMTU Selection and Keying\u003c\/strong\u003e: Align the mechanical keying wheel on the chosen Module Termination Unit (TU810, TU812, TU814, TU818, TU830, or TU833) to match keying code BA before mounting the module to prevent insertion of incompatible hardware.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN-Rail Assembly\u003c\/strong\u003e: Securely latch the Module Termination Unit onto standard 35 mm DIN rails (EN 50022).

Route sensor wires away from high-voltage AC power lines and variable frequency drive outputs. Terminate field cable shields directly at the designated MTU shield terminals, ensuring proper single-point grounding at the control cabinet entry plane to prevent ground loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCold Junction RTD Wiring\u003c\/strong\u003e: When utilizing Channel 8 for local temperature reference, wire the 4-wire Pt100 RTD sensor precisely according to the MTU terminal diagram. Ensure all four leads maintain equal length and resistance to eliminate compensation drift.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Insertion\u003c\/strong\u003e: Slide the AI835A module straight into the MTU connector slot until the locking latches fully engage on both sides.
