Filter searchAD-KEB 20 GX
Description
The two-channel AD-KEB 20 GX is used to read in digital signals that are present as a contact or active 24V signal. The respective signal state is indicated on the device by means of a red LED.
Device communication takes place via the RS485 bus interface and is implemented using the MODBUS RTU protocol.
The power supply and the RS485 bus connection are possible via the rear DIN rail connector. The device is equipped with two rotary coding switches with which the bus address can be set on the device.
An optical search function allows the localization of a single device in a network. For this purpose, the green LED is set in a time-limited flashing mode, between 1 and 255 seconds.
Interface settings as well as the device address can be modified during operation by means of Modbus commands.
All Modbus register addresses and associated commands are listed in the document attachment.
The presettable absolute counters continuously add incoming pulses and are saved in a non-volatile memory every hour.
The current counters are reset during readout to detect subsets.
Application
Reading in digital signals in general electrical engineering,
automation technology and in the water / wastewater sector.
For example: pulse counting with presettable counters or
frequency measurement.
