AD-AEB 40 GT

Description

The AD AEB 40 GT enables a 4-channel analog signal acquisition while providing digitally processed process variables. The signals are provided via an RS485 bus interface available. Analog values and scaling values are available via implemented MODBUS commands. All settings for scaling or filter are carried out via MODBUS commands.
The operating voltage is indicated by a green LED. The data communication is signaled by a yellow LED. Invalid measurement signals outside the defined measuring range are detected. In this case, the green LED flashes.

AD-AEB 40 GT

Application

Conversion of analog process variables in digital information already in the cabinet. Drastic reduction of wiring work.

Specific characteristics

Four analog inputs can be used as voltage or current input. Adjustable filter functions. Electrically isolated RS485 bus interface. Configurable interface settings. Front-setting the device address. Electrically isolated wide range power supply. Programmable with PC via AD-Studio configuration software. Double RS485 BUS connection for wire loop through. Status LED for operating voltage and data communication. Visual indication of an invalid measurement signals.
