【英文介绍】
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 d.c without damage. Current limiting is performed by PTC resistors. The input resistance for current input is 250 ohms, including PTC.
The voltage input can withstand overvoltage or undervoltage of at least 30 V DC. The input resistance is 290k ohms. Transmitter power supplies can be connected to L1+, L1-, and/or L2+, L2-.
