Input PT100 The I61 analog input (H61 and H62) allows connecting a thermocouple (PT100 model) to monitor
the temperature and, in case of activation of the PTC protection (page 69), to manage a TRIP in
case of alarm (fixed threshold at 120°C)
The contact guarantees the following measurement characteristics:
Input
PT100
The I63 digital input (H63 and H64) allows commanding the reopening of the O61 contact
Input Trip reset
following a TRIP.
The module has two logical states, interpreted differently by the Trip unit according to the polarity
configured by the user:
State
Open
Closed
The re-closing command is activated on the front.
Interface The module has four signaling LEDs:

second): module on and not in communication with a trip unit
Indicates the status of the PT100 I61 temperature probe:

Off: input disabled

On: input enabled and sensor present

Blinking: input enabled and sensor disconnected or invalid signal
