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 246).
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
Open Circuit open
(1)
Active open ON
Active closed OFF
Closed Short-circuit
(2)
Active open OFF
Active closed ON
(1)
R > 100 kΩ
(2)
R (wiring + short circuit contact) <25 Ω
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 246).
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

LED Description
Power
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 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
I 11, I 12
Indicate the status of the contacts of each output:
• off: contact open
• on: contact closed
O 11, O 12
Indicate the status of the contacts of each input:
• off: circuit open
• on: short circuit
