•
Electrical isolation between all inputs and from
the electronics: 2.0 kV AC
•
AC/DC operation (any polarity for DC)

b) Binary outputs
The following applies to all 5 output channels:
•
Electrical isolation between all outputs and
from the electronics: 2.0 kV AC
•
Switching voltage: max. 400 V AC or 300 V DC
•
Switching current: max. 6 A / 250 V AC
(resistive)
• ON resistance: 100 mΩ
•
Switch putputs: NOC, NCC and fleeting contact
•
Duration of fleeting contact pulse: 100 ms
•
Output connections: varistors

) In general, with AC signals which are connected via long lines, it should
be checked whether the installed base load of 300 kΩ is sufficient
(mutual capacitive coupling!) to ensure a reliably low interference level.
Otherwise, an appropriately dimensioned resistor or capacitor is to be
connected in parallel at the input terminals.

Protection of power feed (must be ordered):
- Power pack A:
ABB-Stotz m.c.b.: S 282 UC-K; 1.6 A
- Power pack B:
ABB-Stotz m.c.b.: S 282 UC-K; 1.0 A
•
Power consumption on the input side during a
charging process: ca. 100 W
•
Power consumption in normal position: P < 10 W
•
Charging times of the capacitor (example for DC
voltage):
- a) Initial charging on commissioning:
- Breakers up to 25 kA: max. 20s depending on
the supply voltage.
In this time, the capacitor(s) is/are charged to
80 V, and an ON-OFF operating cycle is
already possible at 69 V. (The ”READY” lamp
indicates readiness for switching. A flashing
“READY” lamp signals recharging of the
capacitor. Switching readiness is enabled
during that time).
- b) Recharging after a switch operation to a
charge of 80 V: max. 10s
