Core Specifications
1.Electrical & Signal Termination
Channel Configuration: 16 I/O channels (each with 2 I/O connections + 1 ZP (zero potential) connection) — supports 3-wire field device wiring for analog/digital signals.
Process Voltage:
Maximum rated voltage: 50 V DC (compatible with standard 24 V DC industrial field devices).
Isolation: 2 individually isolated process voltage groups (prevents cross-group interference).
Fusing: Each group includes a 6.3 A fuse (protects against overcurrent in field circuits).
Current Ratings:
Maximum current per I/O channel: 2 A (sufficient for most low-to-medium power field devices).
Maximum current per process connection: 5 A (supports power distribution to multiple field devices per group).
Dielectric Test Voltage: 500 V AC (ensures electrical insulation integrity between terminals and ground).
ModuleBus Support: Integrates a segment of the ModuleBus—distributes the bus from the I/O module to the next TU830V1 and generates unique I/O module addresses by shifting position signals, enabling daisy-chaining of MTUs.
2.Wiring & Mechanical Details
Acceptable Wire Sizes:
Solid conductors: 0.2–4 mm²
Stranded conductors: 0.2–2.5 mm² (24–12 AWG)
Wiring Specifications:
Recommended terminal fastening torque: 0.5–0.6 Nm (ensures secure connections in vibrating environments).
Wire stripping length: 7 mm (optimized for terminal insertion and contact reliability).
Mechanical Keying: Prevents incorrect insertion of incompatible I/O modules—ensures only supported S800 I/O modules can be mated, reducing wiring errors and module damage.
Grounding: Latching device for DIN rail grounding (enhances EMI immunity and electrical safety).
3.Physical Dimensions & Weight
Width: 126 mm (5 in.) including connector; 120.5 mm (4.74 in.) edge-to-edge when installed.
Depth: 64 mm (2.52 in.) including terminals.
Height: 110 mm (4.3 in.).
Net Weight: 0.28 kg (0.6 lbs) — lightweight design minimizes rack load.
Mounting: DIN rail mounting (compliant with EN 50022 standards) with bidirectional installation capability (flexible placement in control cabinets).
4.Environmental & Regulatory Compliance
Operating Temperature Range: 0 °C to +55 °C (+32 °F to +131 °F); certifications apply to +5 °C to +55 °C.
Storage Temperature Range: -40 °C to +70 °C (-40 °F to +158 °F).
Relative Humidity: 5% to 95% (non-condensing) — suitable for humid industrial environments.
Pollution Degree: Degree 2 (IEC 60664-1) — safe for environments with limited dust or moisture.
Corrosion Protection: ISA-S71.04: G3 (resists mild to moderate corrosion, ideal for coastal or chemical plants).
Protection Class: IP20 (IEC 60529) — protects against solid objects ≥12.5 mm (e.g., fingers) and dust ingress.
Certifications:
Electrical Safety: EN 61010-1, UL 61010-1, EN 61010-2-201, UL 61010-2-201.
Hazardous Locations: C1 Div 2 cULus, C1 Zone 2 cULus, ATEX Zone 2.
Marine: ABS, BV, DNV-GL, LR (approved for marine control systems).
EMC: EN 61000-6-4 (emissions), EN 61000-6-2 (immunity).
RoHS: EN 50581:2012 (compliant with EU restrictions on hazardous substances).
WEEE: DIRECTIVE/2012/19/EU (facilitates proper waste recycling).
Key Functional Features
High-Density I/O Termination: 16 channels support a large number of field devices per MTU, reducing the number of termination units needed in high-density S800 I/O racks—saves cabinet space and simplifies wiring.
Isolated Process Power: Two individually isolated process voltage groups prevent ground loops and cross-interference between field circuits (critical for analog signals like 4-20 mA or RTD measurements).
Overcurrent Protection: 6.3 A fuses per power group shield field devices and I/O modules from damage caused by short circuits or overcurrent events.
ModuleBus Extension: Routes the ModuleBus to daisy-chain multiple TU830V1 units and assigns unique addresses to I/O modules—enables scalable I/O configurations without additional bus adapters.
Mechanical Safety: Mechanical keying prevents mismating of incompatible I/O modules, while DIN rail latching ensures secure grounding and stability in vibrating industrial environments (e.g., pump stations, marine vessels).
