ABB 3BSE008516R1 Analog Input Module

家族: S800 I/Oシリーズ, System 800xA / AC800M DCS, 8-channel analog 入力モジュール

基本情報

部品番号: 3BSE008516R1

Short Model Name: AI810

タイプ: アナログ入力, 8CH

Signal Types: 0(4)…20mA, 0…10V, ソフトウェア経由で設定可能

解決: 12-少し, single-ended input

Hot swap supported, online configuration available

HSコード: 85389091

Compatible Terminal Units (TU series, 必須)

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

代表的な用途

Transmitter signal acquisition: プレッシャー, レベル, 流れ, 温度 (4-20ミリアンペア / 0-10V). Widely used in chemical, 力, metallurgy process DCS.

Key Limitations

Single-ended input, differential input not supported; poorer common-mode noise rejection than differential AI modules (例えば. AI830)

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

On-board channel current limiting protection

代替 & Compatibility Reference (同じシリーズ)

Select according to signal requirements:

AI830 (differential type, 優れたノイズ耐性)

AI815 (HART version, 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 チャンネル.

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 チャンネル, configured separately in Control Builder, total channels are cumulative.

例: 2 × AI810 = 16 アナログ入力チャンネル

制約: 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.

補足事項

Channel mode (ミリアンペア / 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 (電流信号, widely used for 2-wire transmitters)
2. 0～10 V (電圧信号)

主な特長

入力タイプ: Single-ended, differential input not supported

解決: 12-少し

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

Does NOT support: 測温抵抗体, TC thermocouple, resistance signal, ハート

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