About product:

The AAI835-H03 S1 is a current input/Output Module that receives and outputs 4-20 mA signals. It is isolated both between the field and the system and between each channel, ensuring safe and reliable operation. When calculating the minimum operating voltage for transmitters connected to this module, it is important to account for the voltage drop in external wiring to ensure the required voltage is met.

This module is designed to operate in temperature environments ranging from 60 to 70°C, with an allowable load resistance between 200 and 750 Ω under such conditions.

In addition to exchanging standard 4-20 mA input/output data with field control stations (FCS), the analog I/O module with HART communication function can also receive HART variables from connected transmitters or valve positioners, providing enhanced communication capabilities.

FAQ:
1. What is the AAI835-H03 S1 module used for?
The AAI835-H03 S1 is a Current Input/Output Module designed to handle 4–20 mA current signals. It can both receive and transmit signals, allowing it to be used for a variety of industrial applications, including communication with transmitters, valve positioners, and other process control equipment.

2. What types of signals does the AAI835-H03 S1 module support?
The module supports 4-20 mA current signals and can receive and output these signals to and from various field devices. It also supports HART communication when used with devices that provide additional digital data along with the analog current signal.

3. Is the module isolated?
Yes, the AAI835-H03 S1 module features channel-to-channel isolation, as well as field-to-system isolation. This helps protect both the module and the system from electrical interference and faults.
