AI810 Analog Input Module – Product Details:
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 limitation is achieved by PTC resistance. The input resistance for current input is 250 ohms, including PTC.
The voltage input can withstand at least 30 V dc overvoltage or undervoltage input resistance of 290k ohms. Transmitter power supplies can be connected to L1+, L1-, and/or L2+, L2-.
Features and advantages
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 resistance is protected to 30V by PTC resistance
Analog input short-circuit protection to ZP or +24 V
