D05125R01.20 F-PRO 116 User Manual 1-5
AC Current Inputs
F-PRO is provided with terminal blocks for up to 5 AC current
inputs (3 Phase Current, 1 Neutral and 1 SEF). 1A and 5A are
separate terminals, 1A / 5A CT Secondary is Site Selectable.
To refer the complete schematic circuits; see “AC Schematic
Drawing” in Appendix-I & “ DC Schematic Drawing” in Appendix-J
External Inputs
The F-PRO relay has 4 external inputs with a factory selectable
voltage level. External DC voltages of either 24/30 volts, 48/50
volts, 110/125 volts or 220/250 volts nominal are available
depending on the ordering code.
Relay Inoperative Alarm
Output
If the relay becomes inoperative, then the Relay Inoperative Alarm
output contact closes. Output Contact 6 may be configured as
Relay Inoperative Alarm Contacts. During the relay inoperative
period, all tripping functions are blocked.
Output Relay Contacts
The F-PRO relay has 6 output relay contacts. Each contact is
programmable and has breaker tripping capability. All output
contacts are isolated from each other. All the contacts are
provided with settable dropout timers (0-1 sec) - applicable for
self reset.
If function reset time & the output contact reset time both are set
in the IED; then, the higher value will be taken for relay drop out.
Example: 51 function is chosen with reset DTL delay 0.5 sec and
the output contact dropout time is 0.8 sec, then 0.8 sec will be the
dropout time of the output contact.
