Depth 102 mm (4.01 “), 111 mm (4.37 “) including connector

Height 119 mm (4.7 in)

Weight 0.23 kg (0.51 lb)

Signal specification: 0… 20 mah, 4… 20 mah, 0… 5 volts, 1… 5 Volts

Number of channels: 8

Signal type: Unipolar single-ended

The AI815 analog input module has 8 channels. These modules can be configured for voltage or current input. Current and voltage signals cannot be mixed on the same I/O module. Voltage and current inputs can withstand overvoltage or undervoltage of at least 11 V DC.

The input resistance of the voltage input is greater than 10 M ohms and the input resistance of the current input is 250 Ω. The module allocates external HART compatible transmitter power to each channel. This adds a simple connection that distributes power to a 2 – or 3-wire transmitter. Transmitter power is monitored and current limited. If an external power supply is used to power the HART transmitter, the power supply must be compatible with HART.

Characteristics and advantages
