Analog Input and Output Functions
The AAI835-H53 combines four analog input channels and four analog output channels in one module. The input channels receive 4-20 mA signals from field instruments, while the output channels transmit 4-20 mA signals to connected field devices.
Furthermore, the isolated channel design separates the analog signal circuits. The specified 500 V AC withstand voltage for 1 minute defines the insulation test condition between the input/output circuits and the system, as well as between input/output channels.
Output Characteristics
The output channels support load resistance from 0 to 750 ohm, with an output leakage current below 0.65 mA. The specified output accuracy is +/-48 uA.
Meanwhile, the output voltage limit is 29.3 V or less at 0 mA. These values are relevant when checking the electrical requirements of connected field devices and signal wiring.
Model Configuration
The AAI835-H53 suffix identifies the following configuration:
| Code | Specification |
|---|---|
| AAI835 | 4-channel input / 4-channel output analog I/O module |
| H | With HART digital communication |
| 5 | Without explosion protection |
| 3 | ISA Standard G3 option and temperature option (-20 to 70 deg C) |
Therefore, AAI835-H53 is the HART communication version without explosion protection, configured with the ISA Standard G3 and extended temperature options.
Frequently Asked Questions
Q: Does the AAI835-H53 support HART communication?
A: Yes. The H suffix identifies the HART digital communication configuration, in addition to the standard 4-20 mA analog signal functions.
Q: Does the AAI835-H53 include explosion protection?
A: No. The suffix 5 specifies the version without explosion protection. It should not be confused with the E suffix configuration.
Q: What is the operating temperature option for the AAI835-H53?
A: The suffix 3 identifies the extended temperature option, with a specified range of -20 to 70 deg C, together with the ISA Standard G3 option.
