Supporting up to 8 analog input channels rated at 50 V and 2 A per channel, the unit provides direct connection points for AI810, AI815, and AI845 modules. The termination unit routes ModuleBus signals to the attached module while shifting position signals to derive the correct hardware address for the next adjacent MTU on the DIN rail.\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\u003eTU835V1\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\u003eChina\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eStandard MTU Base Weight (approx. 0.28 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard MTU Base (approx. 126 mm x 110 mm x 64 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\u003ePassive base structure (Driven by ModuleBus and loop power)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Count\u003c\/td\u003e\n\u003ctd\u003eUp to 8 I\/O channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Voltage\u003c\/td\u003e\n\u003ctd\u003e50 V max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Current\u003c\/td\u003e\n\u003ctd\u003e2 A max per channel (8 A max process connection)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransducer Power\u003c\/td\u003e\n\u003ctd\u003eFused transducer power terminal per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProcess Power Isolation\u003c\/td\u003e\n\u003ctd\u003e2 individually isolated process voltage groups\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Modules\u003c\/td\u003e\n\u003ctd\u003eAI810, AI815, AI845\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWire Size Range\u003c\/td\u003e\n\u003ctd\u003eSolid: 0.2 to 4 mm squared; Stranded: 0.2 to 2.5 mm squared \/ 24 to 12 AWG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Screw Torque\u003c\/td\u003e\n\u003ctd\u003e0.5 to 0.6 Nm\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 Mechanical Keying\u003c\/h3\u003e\n\u003cp\u003eThe TU835V1 passes high-speed ModuleBus lines across the backplane without signal attenuation, maintaining fast communication loops across all connected S800 I\/O modules. Positional address shifting logic executes automatically through the internal wiring structure, guaranteeing deterministic address propagation as each MTU attaches to the DIN rail chain. Dual 6-position keying switches prevent operator insertion errors by offering 36 mechanical slot combinations to enforce hardware alignment for AI810, AI815, or AI845 analog modules.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the TU835V1 protect transmitter loop power on individual channels?\u003c\/p\u003e\n\u003cp\u003eA: The base unit provides a fused transducer power terminal for each of its 8 channels. Short circuits or field wiring faults on one transmitter loop remain isolated to that specific terminal line, protecting adjacent field instrumentation and backplane electronics.\u003c\/p\u003e\n\u003cp\u003eQ: Can the TU835V1 be used in redundant S800 analog input configurations?\u003c\/p\u003e\n\u003cp\u003eA: No. The TU835V1 features a single-I\/O base layout designed strictly for non-redundant analog input applications. Redundant analog input architectures require dual-channel base units like the TU842 or TU843.\u003c\/p\u003e\n\u003cp\u003eQ: How does the DIN-rail latching mechanism handle system grounding?\u003c\/p\u003e\n\u003cp\u003eA: The spring-loaded mechanical latch locks the unit onto standard 35 mm DIN rails while simultaneously engaging integral conductive grounding contacts to link the MTU backplane ground directly to the rail surface.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN Rail Mounting\u003c\/strong\u003e: Mount the TU835V1 onto a standard 35 mm DIN rail (EN 50022).
