8-fold analogue/binary input
INPUTS
Description
The Ekinex® EK-CA1-TP binary input has 8 independent input channels for connecting to
the KNX bus commands and sensors of traditional type, having potential-free contacts or
NTC passive temperature sensor. Thanks to the binary input, it is possible to command
and control bus functions with standard switches, pushbuttons or sensors (not natively
communicating with the KNX bus) or binary signals made available by other devices. The
query voltage of input channels is produced within the device. The device integrates a KNX
bus communication module and is realized for mounting on a standard 35 mm DIN-rail.
The device is supplied by the KNX bus and does not require auxiliary power supply.
Main features
• Plastic casing
• ON/OFF switching of single loads or group of loads
• Detecting the state of signaling contacts (from safety devices, alarms, etc.)
• Recalling and saving of scenes
• Sending on the bus of values (temperature, brightness, etc.)
