ABB 3BSE008516R1 Analog Input Module

Famille: Série E/S S800, System 800xA / AC800M DCS, 8-channel analog module d'entrée

Informations de base

Numéro de pièce.: 3BSE008516R1

Short Model Name: AI810

Taper: Entrée analogique, 8CH

Types de signaux: 0(4)…20mA, 0…10V, configurable via software

Résolution: 12-peu, single-ended input

Hot swap supported, online configuration available

Code SH: 85389091

Compatible Terminal Units (TU series, obligatoire)

TU810 / TU812 / TU814 / TU818 / TU830 / TU833 / TU835 / TU838 / TU850

Applications typiques

Transmitter signal acquisition: pression, niveau, couler, température (4-20mA / 0-10V). Widely used in chemical, pouvoir, metallurgy process DCS.

Key Limitations

Entrée asymétrique, differential input not supported; poorer common-mode noise rejection than differential AI modules (par exemple. AI830)

Passive acquisition, no transmitter power supply from module itself. 2-wire transmitters require external 24V supply

On-board channel current limiting protection

Alternative & Compatibility Reference (Même série)

Select according to signal requirements:

AI830 (differential type, superior noise immunity)

AI815 (Version HART, supports HART protocol transmitters)

Troublshooting Guide

1. No reading: Verify terminal unit model, Profibus DP communication, and channel configuration (mA or V)
2. Fluctuating signal: Single-ended design. Priority check shield grounding; avoid routing alongside power cables
3. Module without fault alarm but fixed reading: Check transmitter power supply and loop continuity

A single AI810 has fixed 8 hardware channels. No jumper, software setting or accessory can expand one AI810 to more than 8 chaînes.

Two Valid Expansion Methods within S800 I/O System

1. Add extra AI810 or other AI modules in the series

S800 I/O is distributed bus I/O. Multiple I/O stations and multiple AI810/AI815/AI830 modules on one backplane can be connected to a Profibus DP bus. Each module works independently with 8 chaînes, configured separately in Control Builder, total channels are cumulative.

Exemple: 2 × AI810 = 16 canaux d'entrée analogiques

Contraintes: Profibus bus load, controller I/O capacity, available backplane slots

2. Replace with higher-density modules

Most standard S800 AI modules are 8-channel; no 16-channel analog input module available in S800 range.

For HART: AI815 (also 8CH, HART capable)

For high noise & long cable runs: AI830 (8CH differential)

❌ Not Recommended Workarounds

Signal splitter / signal shunt: One transmitter signal split into two AI channels. Readings are identical, no new measurement point, accuracy degraded. Not acceptable for formal DCS application.

TU terminal units are only for wiring, no channel expansion function, only signal transfer and isolation.

Notes complémentaires

Channel mode (mA / V) is changed only by software configuration, channel count remains unchanged. Hot swap and online configuration apply per module and cannot increase channel quantity.

Signals Supported by ABB AI810 (3BSE008516R1)

✅ Only 2 signal types, configurable per channel independently via software

1. 0(4)～20 mA (signal actuel, widely used for 2-wire transmitters)
2. 0～10 V (signal de tension)

Principales fonctionnalités

Type d'entrée: Single-ended, differential input not supported

Résolution: 12-peu

Passive module, cannot supply power to transmitters externally. 4-20mA 2-wire transmitters require external 24V DC supply

Does NOT support: RDT, TC thermocouple, signal de résistance, CERF

Each channel may be set to mA or V separately; mixed mA/V channels are allowed on one module
