AI845 analog input module for single or redundant applications. The module has 8 channels. When MTU TU844 or TU845 is used, each channel can be a voltage or current input, and when other Mtus are used, all channels become voltage or current inputs.

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.

Characteristics and advantages

8 channels for 0… 20 mA, 4… 20 mA, 0… 5 V or 1… 5 V DC, single-ended unipolar input

Single or redundant operation

1 group of 8 channels, isolated from the ground

12-bit resolution

Each channel current limits the transmitter power supply

Advanced on-board diagnostics

HART direct communication
