Power Supply
Auxiliary Voltage (Vx)
Three ordering options:
(i) Vx: 24 to 48 Vdc
(ii) Vx: 48 to 110 Vdc, and 30 to
100Vac
(rms)
(iii) Vx: 110 to 250 Vdc, and 100 to
240Vac
(rms)
Operating Range
(i) 19 to 65V (dc only for this variant)
(ii) 37 to 150V (dc), 24 to 110V (ac)
(iii) 87 to 300V (dc), 80 to 265V (ac)
With a tolerable ac ripple of up to 12% for a dc
supply, per IEC 60255-11: 1979.
Nominal Burden
Quiescent burden: 11W. (Extra 1.25W when
fitted with second rear Courier)
Additions for energized binary inputs/outputs:
Per opto input:
0.09W (24 to 54V),
0.12W (110/125V),
0.19W (220/120V).
Per energized output relay: 0.13W
Power-up Time
Time to power up < 11s.
Power Supply Interruption
Per IEC 60255-11: 1979
The relay will withstand a 20ms interruption
in the DC auxiliary supply, without
de-energizing.
Per IEC 61000-4-11: 1994
The relay will withstand a 20ms interruption
in an AC auxiliary supply, without
de-energizing.
Battery Backup
Front panel mounted
Type ½ AA, 3.6V (SAFT advanced battery
reference LS14250)
