1. General Introduction
The AI815 Analog Input Module has 8 channels. The modules can be configured for voltage or current inputs. Current and voltage signals cannot be mixed on the same I/O module. The voltage and current input is able to withstand an overvoltage or under voltage of at least 11 V d.c.
The input resistance for voltage input is greater than 10 M ohm, and the input resistance for current input is 250 ohm. The module distributes the external HART compatible transmitter supply to each channel. This adds a simple connection to distribute the supply to 2-wire or 3-wire transmitters. The transmitter power is supervised and current limited. If an external power supply is used for feeding HART transmitters, the power supply must be HART compatible.
