【功能描述】
AI810 8 通道模擬量輸入模塊 ABB
AI810 8通道模擬量輸入模塊的優(yōu)勢(shì)：
特點(diǎn)和好處
8 個(gè)通道，用于 0…20 mA、4…20 mA、0…10 V 或 2…10 V dc，單端單極輸入
1組8通道與地隔離
12 位分辨率
輸入分流電阻器由 PTC 電阻器保護(hù)至 30 V
模擬輸入短路保護(hù)至 ZP 或 +24 V
輸入承受 HART 通訊。
AI810 模擬量輸入模塊有 8 個(gè)通道。每個(gè)通道可以是電壓或電流輸入。電流輸入能夠處理至少 30 V dc 的變送器電源短路而不會(huì)損壞。電流限制是通過(guò)一個(gè) PTC 電阻來(lái)執(zhí)行的。電流輸入的輸入電阻為 250 歐姆，包括 PTC。

【英文介紹】
AI810 8-channel analog input module ABB
Benefits of the AI810 8-channel analog input module:
Features and benefits
8 channels for 0... 20 mA, 4... 20 mA, 0... 10 V or 2... 10 V dc, single-ended single-pole input
One group of eight channels is isolated from the ground
12-bit resolution
The input shunt resistor is protected to 30 V by a PTC resistor
Analog input short-circuit protection to ZP or +24 V
Input receives HART communication.
The AI810 analog input module has eight channels. Each channel can be a voltage or current input. The current input is capable of handling a short circuit in the transmitter power supply of at least 30 V dc without damage. Current limiting is performed by a PTC resistor. The input resistance for current input is 250 ohms, including PTC.
