AI880A 高完整性模擬量輸入模塊專為單一和冗余配置而設(shè)計(jì)。該模塊具有 8 個(gè)電流輸入通道。輸入電阻為 250 歐姆。
該模塊將外部變送器電源分配到每個(gè)通道。這增加了一個(gè)簡單的連接，將電源分配到 2 線或 3 線制變送器。變送器功率受到監(jiān)控并限制電流。所有 8 個(gè)通道都與 ModuleBus 隔離在一個(gè)組中。模塊的電源由ModuleBus上的24 V產(chǎn)生。
AI880A 符合 NAMUR 建議 NE43，并支持可配置的超量程和欠限。

AI880A 3BSE039293R1 | Analog input module | SNAT607 MCI | NTAI06
Model: AI880A 3BSE039293R1
Category: Analog input module
Finish: New/not new
Warranty: One year
Express: SF Express/Debon
The AI880A High integrity analog input module is designed for single and redundant configurations. The module has 8 current input channels. The input resistance is 250 ohms.
This module distributes external transmitter power to each channel. This adds a simple connection to distribute power to a 2 - or 3-wire transmitter. Transmitter power is monitored and current is limited. All eight channels are isolated from the ModuleBus in a group. The power supply for the module is generated by 24 V on the ModuleBus.
The AI880A complies with NAMUR recommendation NE43 and supports configurable overranges and underlimits.
Characteristics and advantages
8 channels for 0... 20 mA, 4... 20 mA, single-ended unipolar input
Single or redundant configuration
1 group of 8 channels, isolated from the ground
12-bit resolution
Loop monitors the DI function
Alarm limits for field power output can be configured
Configurable over/under range of current input
Each channel has a limited transmitter current
Advanced onboard diagnostics
Certified by IEC 61508 SIL3
Category 4 certified according to EN 954-1
Complies with NAMUR recommendation NE43 and supports configurable overranges and underlimits
