Below is a description of the connectors supplied with the EVD00004*0 or purchased in separate
packages (EVD400CON0 for the EVD00004*1). The drawings represent the connectors as seen after
having been fi tted on the EVD
4 .
2.1 Power supply, sensors, digital I/O
The main 14-pin MINIFIT ® connector is used to connect the main and auxiliary power supply (if the
EVBAT00200/300 module is fi tted), as well as the sensors, digital inputs and transistor output.
This connector accepts wires with cross-section up to 1 mm
2
with MOLEX
®
5556-T barrel.
A kit of pre-crimped 14 x 1 mm 2 cables, length 5 m, is available for purchase (EVDCAB0500).
line Function
G, G0 24 Vac power supply
GND Earth for all signals, in electrical contact with GND and the GNX terminal on the main serial
connector
Vbat Emergency power supply generated by the EVBAT00200 module
DI1, DI2 Digital inputs to be activated by voltage-free contact or transistor to GND, 5 V no-load and 5
mA short-circuited
Vr1, Vr2 5 V references used as power supply to the ratiometric probes
S1 Analogue input for ratiometric probe or NTC low temperature probe
S2 Analogue input for ratiometric probe, NTC high temperature probe or Pt1000
S3 Analogue input for ratiometric probe or NTC low temperature probe
S4I Analogue input for 4 to 20 mA signal
S4V Analogue input for 0 to 10 Volt signal
OC Open-collector transistor output, for up to 100 mA

)
Removable terminal for connection to the MASTER unit (µChiller, pCO) or the supervisor (PlantVisor).
line Function
GNX Signal earth, in electrical contact with GND on the I/O connector
RT+ + signal for the RS485 connection (pLAN, supervisor, Modbus
