Power supply Ekip Com Signalling 2K is supplied directly by the Ekip Supply module to which it is connected.
NOTE: communication between Ekip Touch and the module is interrupted in the absence of
auxiliary power supply

Input Ekip Touch can be configured so that the status of the inputs corresponds to actions or signals, with different
programming options (page 222).
The connection of each input (H11 and H12 for model 2K-1, H21 and H22 for model 2K-2, H31 and H32 for
model 2K-3) must be made with reference to the common contacts (HC).
The module permits two logic statuses, interpreted differently by Ekip Touch depending on the configuration
selected for each contact:
State Electrical condition Contact configuration Status detected by Trip unit
Active open ON
Open Circuit open
Active closed OFF
Active open OFF
Closed Short-circuit
Active closed ON

Output Ekip Touch can be configured so that the contacts of each output are closed or opened upon the occurrence
of one or more events, with different programming options (page 222).
The output of each module consists of 2 contacts (K11-K12 and K13-K14 for model 2K-1; K21-K22 and
K23-K24 for model 2K-2; K31-K32 and K33-K34 for model 2K-3), which are isolated from the unit and from
the other outputs, and have the following electrical characteristics:
Characteristics Maximum limit (1)
Maximum switchable voltage 150 VDC / 250 VAC
2 A @ 30 VDC, 0,8 A @ 50 VDC, 0,2 A @ 150 VDC,
Breaking capacity
4A @ 250 VAC
Dielectric strength between open contacts 1000 V AC (1 minute @ 50 Hz).
Dielectric strength between each contact and coil 1000 V AC (1 minute @ 50 Hz).

Interface the module has three signaling leds:

Figure 135

LEDs Description
Signals the on status and correct communication with Ekip Touch:
• off: module off
• on steady or flashing synchronized with the Power led of Ekip Touch: module on
Power
and communication with Trip unit present.
• flashing not synchronized with the Power led of Ekip Touch (2 fast flashes per
second): module on and communication with Trip unit absent.
Indicate the status of the contacts of each output:
I 11, I 12 • off: contact open
• on: contact closed
Indicate the status of the contacts of each input:
O 11, O 12 • off: circuit open
• on: short circuit
