Digital I/O module KET-DDX-410

Modbus RTURS4854 digital inputs

The KET-DDX-410, designed for the realisation of control systems used in building automation, is an I/O module with 4 digital inputs for dry contact (max 30 Hz) and 4 digital SPDT relay outputs type NC C NO with capacity 12 A @ 250 VAC, 12 A @ 24 VDC and maximum peak current up to 100 A. 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-410 supports RS485 serial communication with ModBUS RTU Slave protocol. Its DIN-rail mounting and removable spring terminals make it easy to install in any industrial switchboard.
