Products | KET-DDX-411

Wireless multifunction I/O module with 4 digital inputs and 4 relay outputs

The KET-DDX-411 manages up to 32 ModBUS RTU slave devices connected to its RS485 port. It can be programmed to read a series of registers and send them to the Gateway.

It is designed for control systems used in building automation with the I/O module with 4 digital inputs for dry contact (max 30 Hz) and 4 digital outputs SPDT relays type NC C NO with capacity 12 A @ 250 VAC, 12 A @ 24 VDC and maximum peak current up to 100 A, ModBUS Master wireless with X-Monitor communication protocol.

It is equipped with a 4-LED interface to display the status of each input/output selectable via a handy keypad and an F-RAM memory for maintaining configured parameters in the event of a power failure.

The KET-DDX-411 is equipped with a 2.4 GHz ISM band radio module that allows for a free air signal range of up to 1000 m, which is essential for large installations because it avoids the placement of numerous metres of cable, reducing costs.

DIN rail mounting and removable spring terminals make it easy to install in any industrial control cabinet.
