ModBUS multifunctional mixed I/O module with 4 digital inputs, 2 RTD inputs and 4 relay outputs
The KET-DDX-410, designed for the realization of control systems for cooling and heating systems, is an I/O module with 2 inputs for PT1000 resistance thermometers, 4 digital inputs for clean 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 inrush current up to 100 A.
It is equipped with an interface with 4 leds to display the status of each input/output selectable through a practical keyboard and with an F-RAM memory to maintain the configured parameters in case of power failure.
The KET-DDX-410 supports RS485 serial communication with MoDBUS RTU Slave protocol.
DIN rail mounting and removable spring clamp terminals make it easy to install in any industrial control cabinet.
