15 - Ekip Signalling 3T

Ekip Signalling 3T is a signaling accessory which enables the connection of:
• three analog inputs for PT100/PT1000 temperature sensors (2 wires): I42, I43, I44
• an analog input for 4-20 mA current loop: I41
The measurements supplied by the module can be associated with different control threshold, useful for
configuring alarm signals, states and programmable commands.
Accessories Ekip Cartridge and Ekip Supply are required in order to connect Ekip Signalling 3T to Ekip
Touch (page 122, 123).

Models Ekip Touch can be configured with two different 3T modules: Ekip Signalling 3T-1 and Ekip Signalling 3T-2.
NOTE: if different indications are not given, the information in the next chapter is valid for
both models; on the second module the inputs are called I51 (lopp 4-20 mA), I52, I53, I54
(PT100/PT1000)
The two modules can be installed at the same time on the same circuit-breaker so as to extend the
opportunities for measuring and monitoring the installation.
IMPORTANT: each circuit-breaker can only be fitted with one module per type. Configuration
with two modules of the same model is not allowed (example: two Ekip Signalling 3T-1
modules)

Connections For references about the connection and terminals, please consult document 1SdM000068r0001
To connect the module to Ekip Touch, please consult document 1SdH001000r0527.
For PT100/PT1000 sensors, use insulated cables for resistance thermometers such as PENTRONIC TEC/
SITW-24F (Type TX) or similar. Maximum length 3 meters.
For the 4-20 mA Current Loop sensor, use suitable cables up to 3 meters in length compatible with the
workplace in which the 4-20 mA current sensor is used.
IMPORTANT: the inputs are not insulated: regardless of plant voltage, the customer must
ensure there is insulation between each input and between the inputs and power supply
of the Ekip Supply module on the basis of the customer's own application and network.
For applications in low voltage installations ABB suggests use of the external probe
PT1000 3mt, is equippped with a nut and screw for use on busbars and is compatible
with the dielectric withstand and insulation levels established by standard IEC 60947-2
(Ui= 1000 V, Uimp= 12 kV).

Power supply Ekip Signalling 3T 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 The module enables the following quantities to be measured

Input Measurement Range Resolution Accuracy (1)
PT100/PT1000 Temperature -50 ÷ 250 °C (2) 0,01 °C ± 1 °C (5)
Current loop 4-20 mA DC current 0 ÷ 100 % (3) 0.1 % ± 0,5 % (4)

(1) accuracy values refer to 3T module without sensors. For complete accuracy, consider the
characteristics of the sensors and cabling used; accuracy increases by 0.5 °C with the ABB sensor
(2) with ABB PT1000 sensor, the range is -25 ÷ 150 °C
(3) the measurement is expressed as a percentage, where: 0% = 4 mA and 100% = 20 mA
(4) accuracy values refer to full scale: 0.5%= 0.1 mA
(5) Accuracy valid within the 0 to 130 °C range with module at 25 °C ambient temperature. The
accuracy value is ± 2 °C over the whole range, with module at 25 °C ambient temperature
