P341 Software versions 36 & 71J
Power-up time
Time to power up < 11 s.
Power supply interruption
3 power supply options:
(i) Vx: 24 to 48 V dc
(ii) Vx: 48 to 110 V dc, 40 to 100 V ac (rms)
(iii) (i) Vx: 110 to 250 V dc, 100 to 240 V ac
(rms)
Per IEC 60255-11: 2008
The relay will withstand a 100% interruption in
the DC supply without de-energizing as
follows:
(i) Vx: 24 to 48 V dc
Quescent / half load
20 ms at 24 V
50 ms at 36 V
100 ms at 48 V
maximum loading:
20 ms at 24 V
50 ms at 36 V
100 ms at 48 V
(ii) Vx: 48 to 110 V dc
Quescent / half load
20 ms at 36 V
50 ms at 60 V
100 ms at 72 V
200 ms at 110 V
maximum loading:
20 ms at 36 V
50 ms at 60 V
100 ms at 85 V
200 ms at 110 V
(iii) (i) Vx: 110 to 250 V dc
Quescent / half load
50 ms at 110 V
100 ms at 160 V
200 ms at 210 V
maximum loading:
20 ms at 85 V
50 ms at 98 V
100 ms at 135 V
200 ms at 174 V
Per IEC 60255-11: 2008:
The relay will withstand an interruption in the
AC supply without de-energizing as follows:
(ii) Vx = 40 to 100 V ac
Quescent / half load
50 ms at 27 V for 100% voltage dip
maximum loading:
10 ms at 27 V for 100% voltage dip
(iii) Vx = 100 to 240 V ac
Quescent / half load
50 ms at 80 V for 100% voltage dip
maximum loading:
50 ms at 80 V for 100% voltage dip
Maximum loading = all digital inputs/outputs
energized
Quescent or 1/2 loading = 1/2 of all digital
inputs/outputs energized
