Load monitoring
and control interface
UNIVERSAL INTERFACES
Description
The Ekinex® EK-CF2-TP interface for load monitoring and control is a KNX devices
which can be used to:
- measure the instantaneous current absorbed by (up to) three single-phase or one
three-phase electrical circuits;
- control electrical loads with priority disconnection and reconnection.
The current measurement is performed by means of max three Ekinex® EK-TA-...
current transformers. The device is powered by the KNX bus and does not require
auxiliary power supply. Flush-mounting or mounting on a standard 35 mm DIN-rail
by means of a support included in the delivery.
Main features
• Plastic casing
• Programming pushbutton and LED on the case
• Connection to bus line with KNX terminal block
• Connection to current transformers by means of a 6-wire screw terminal block
• IP20 protection degree (installed device)
• Weight 20 g
Functional characteristics
• Connection to current transformers EK-TA-... by means of 3 physical inputs
• Possibility to measure (up to) three single-phase or one three-phase lines;
• Possibility to receive power values from bus
• 8 general purpose power thresholds
• 4 4-channel logic functions (AND, OR or XOR)
Load monitoring
• Direct measurement of instantaneous current by means of transformers EK-TA-...
• Calculation of instantaneous power
• Total electricity metering
• Sending on the bus of measured current, power and energy values
Load control
• Possibility to independently handle up to 8 loads for each channel
• Configurable power threshold for load control and related hysteresis
• Sending on the bus of an indication when the threshold is reached
• Possibility to exclude loads from the bus
• Disconnection and reconnection delay independently configurable for each channel
Power supply
• 30 Vdc power supply by KNX bus
• Current consumption from bus < 10 mA
Delivery
Delivery includes a terminal block for connection to the bus and a support for
mounting on a standard 35 mm DIN-rail. Current transformers EK-TA-... (page 151)
must be ordered separately.

UNIVERSAL INTERFACES
Description
The Ekinex® universal interface is a KNX device which can be used as input and/or
output module. The device is equipped with:
- 4 inputs to connect the KNX bus to switches, pushbuttons or classic sensors
(normally not communicating on the KNX bus) or any binary signals from other
devices, in order to control KNX bus functions. In addition, one input is configurable
as analog to connect a NTC temperature sensor (10 k a 25 °C);
- 2 5A relay outputs to be used as electrical load control (independent) or paired for
shutter and blind actuator control.
The voltage for polling the inputs is supplied within the device. The device integrates
a KNX bus communication module and is realized for flush-mounting or for mounting
on a standard 35 mm DIN-rail. The device is powered by the KNX bus and does not
require auxiliary power supply.
Main features
• Plastic casing
• Programming pushbutton and LED on the case
• Connection to bus line with KNX terminal block
• Screw terminal blocks for connecting inputs and outputs
• IP20 protection degree (installed device)
• Weight 35 g
Power supply
• 30 Vdc power supply by KNX bus
• Current consumption from bus < 10 mA
Delivery
Delivery includes a terminal block for connection to the bus. The NTC temperature
sensors (page 231) for those channels configured as [AI] must be ordered separately.
Accessories
Support for mounting on a standard 35 mm DIN-rail (code EK-SMG-35) and spring
for snapping on the back of Ekinex® wall-mount devices (code EK-MAR-...) to be
ordered separately.
