AD-KAB 10 GX

Description

The AD-KAB10 GX provides a remote controllable relay switching contact (changeover contact). Remote control is via the RS-485 bus interface. The device communication is realized using the MODBUS RTU protocol.
The power supply and the RS485 bus connection is 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.
The static contact control is carried out with a control value 0 or 1.
A pulse output function (with 1 Hz) is triggered with a control value of 1 to 255 and can be modified or stopped at any time with other values. An optical search function allows the localization of a single device in a device network when in a cabinet several devices are on a top hat rail. For this purpose, the green LED is set in a time-limited flashing mode, between 1 and 255 seconds.
For the relay, a defined start state can be set so that when the supply voltage returns after a power failure, a system can assume the desired start state.
The 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.
