describe

The A-AI-1 and A-IAI-1 additional digital displays are ideal solutions for on-site display and synchronous signal transmission.

Due to its open programmability and easy installation, the additional digital display can be easily and quickly added to the system even after the transmitter has been put into operation. In addition, the digital display instrument does not require an additional power supply.

The instrument can be configured using the three buttons located below the front panel. The menu structure design of this digital display instrument is reasonable, and the LCD screen has simple characters that can provide all necessary programming guidance for the operator. Users can set the display range or simultaneously adjust the offset and slope. In addition, users can activate the filter and set it at different stages when necessary. Filters can suppress short-term spike signals, making the display simple and easy to read.

All programmed parameters are saved in EEPROM and will not be lost even in the event of a power outage.

The A-IAI-1 additional digital display instrument is developed specifically for hazardous area applications and can be used in combination with Ex transmitters, Ex transmitter power supplies, or Ex electrical isolation insulation devices, making it suitable for explosion-proof Zone 1.

The additional digital display instrument integrates self diagnostic function to continuously monitor whether the key components of the equipment are operating normally. The integrated self diagnostic function and reporting when the upper or lower limit is exceeded make the instrument highly safe to operate.

The additional digital display instrument features a sturdy and durable compact plastic casing, with a protection level of up to IP 65, making it ideal for various industrial applications.
