Product Precautions
- ABB TU835V1 3BSE013236R1 organizes analog field wiring into two isolated process-power groups while carrying ModuleBus communication through the station. Mechanical keying keeps the fitted I/O module aligned with the intended terminal arrangement.
Signal capacity: Eight I/O channels
Electrical limits: 50 V rated voltage and 2 A per channel
Power grouping: Two individually isolated groups
Electrical limits: 50 V rated voltage and 2 A per channel
Power grouping: Two individually isolated groups
Each of the eight channels provides one signal connection and one fused transducer-power connection. The process supply can be divided into two independently isolated groups. A 2 A channel rating and an 8 A process-connection limit must both be respected; the channel limits do not make a common supply terminal suitable for the sum of all channel maxima.
The termination unit distributes ModuleBus to its fitted I/O module and onward to the next MTU. Position signals are shifted to establish the module address. AI810, AI815 and AI845 are supported in single-I/O arrangements. Two six-position mechanical keys provide 36 combinations to prevent an incorrect module from being inserted; they do not change the electronic function.
The DIN-rail latch secures the MTU and provides its grounding connection. Field terminals accept solid conductors from 0.2 to 4 mm² or stranded conductors from 0.2 to 2.5 mm², with 7 mm stripped length and 0.5–0.6 N·m tightening torque. The unit has IP20 protection and requires a non-condensing environment; the stated operating range is 0 to +55 °C, while approvals apply from +5 to +55 °C.

System and supply context: The MTU interfaces field signals and process power to a compatible AI810, AI815 or AI845 module. The I/O module and neighboring station hardware are separate items unless included in the quotation.
Application scope: Use the unit for single S800 I/O termination arrangements. Conversion accuracy, ranges and channel diagnostics belong to the selected I/O module and must be checked separately.

Fused transducer supply
Bring each sensor power connection through its fused terminal while keeping the associated signal connection identifiable.Separated power groups
Organize two isolated process-supply groups without bridging their returns through unintended field wiring.Single analog I/O stations
Connect compatible AI810, AI815 or AI845 modules through a mechanically keyed field-wiring base.Station maintenance
Preserve field-terminal assignment while checking the fitted module, rail grounding and ModuleBus continuity.
Prepare ABB TU835V1 3BSE013236R1 for its configured installation using these checks.
Isolate field power
Identify both supply groups and isolate them before disturbing field terminals.
Set the keys
Set both mechanical keys for the intended module before inserting it; never force a mismatch.
Respect common limits
Check channel loading and the 8 A process-connection limit separately.
Terminate correctly
Use the specified conductor range, 7 mm strip length and 0.5–0.6 N·m torque.
Secure the rail latch
Confirm mechanical engagement and the intended DIN-rail grounding path.
Check the environment
Provide suitable enclosure protection for IP20 equipment and prevent condensation.

Technical notes
Power distribution: Evaluate the two isolated groups, 2 A channel limit and 8 A process-connection limit together.
Module relationship: Mechanical keys and ModuleBus position signals establish the intended module location; input accuracy is determined by the fitted I/O module.

FAQ View All FAQ
-
How do the two supply groups in TU835V1 3BSE013236R1 help separate field circuits?The process voltage can feed two individually isolated groups. Preserve that separation in the external power and return wiring; an unintended bridge defeats the intended grouping.
-
Can every channel on TU835V1 3BSE013236R1 draw 2 A through one process connection?No. The 2 A limit applies per I/O channel, while the maximum current through a process connection is 8 A. Evaluate the shared connection loading as well as each channel.
-
Does changing the keys on TU835V1 3BSE013236R1 change the input measurement function?No. The two six-position keys provide mechanical coding only. They prevent an unsuitable module from being inserted and do not alter the MTU or I/O-module electronics.
-
Which analog modules can use TU835V1 3BSE013236R1 in a single-I/O station?AI810, AI815 and AI845 can use this MTU in single-I/O arrangements. Their measurement functions and configured ranges remain properties of the selected I/O module.
-
How does TU835V1 3BSE013236R1 establish its I/O module position on ModuleBus?It passes ModuleBus to the module and the next MTU, shifting the outgoing position signals so that the installed module receives the correct position address.
-
What conductor preparation is required at the terminals of TU835V1 3BSE013236R1?Use 0.2–4 mm² solid or 0.2–2.5 mm² stranded conductors. Strip 7 mm and tighten the connection to 0.5–0.6 N·m, keeping loose strands clear of adjacent terminals.
-
Why must the DIN-rail latch on TU835V1 3BSE013236R1 be fully engaged?The latch locks the MTU to the standard DIN rail and supports the grounding connection. Check both secure engagement and the cabinet grounding arrangement before energization.
-
Can TU835V1 3BSE013236R1 operate in a condensing cabinet?No. The humidity range is 5–95% RH without condensation, and protection is IP20. Use an enclosure and environmental controls appropriate to those limits.
