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.
