5.7.1.2.2 Technical Data
Binary outputs
8 binary outputs
(relay)
• 4 groups with 2 outputs each
• Each relay has a 1-pole normally-open contact
• The outputs are galvanically insulated from logic circuits and
ground by monostable relays with double insulation
• Each group is galvanically insulated from the other groups,
logic circuits and ground with double insulation
• Within the groups the outputs are galvanically insulated with
operational insulation (250 kV)
• The Outputs can be used for switching of direct voltage or also
alternating voltage
• Function and status of the outputs via display
Nominal voltage
• 24/48/60/110/220 VDC
• 110/230 VAC
Maximum continuous current Standard circuitry
• 8 outputs max. 2 A each (5 A/1 min)
Circuitry with derating resp. for switching capacity 6 A
*)
• 4 outputs max. 3 A each, 4 outputs max. 1 A each
Circuitry with derating at 5 A
• 1 output max. 5 A, 7 outputs max. 1 A each
• 2 output max. 5 A each, 6 outputs max. 0 A each (relay must
not be activated)
Switching capacity DC voltage
• Min. 50 mW at 5 VDC
• Max. acc. to diagram
AC voltage
• Max. 1250 VA 5 A/250 VAC, resistive load
• Max. 500 VA 2 A/250 VAC, cosϕ = 0.4
Switching cycles
• 3x10
4
Output circuits Max. 250 VDC/253 VAC (operated with an external voltage)
Rated impulse voltage 4 kV
Connectors
Terminals Removable screw terminals (grid size 5.08)
*)
with parallel connection
• For power augmentation 2 relays may be connected parallel, this must happen within one
group (applies only for I < 6 A → 2 x 3 A)
• Groups with parallel connection must not be next to another
• Next to a group with parallel connection outputs may be loaded only with ≤ 2 A
• Outputs that are loaded with > 3 A must not be next to another;
exception: with power augmentation the outputs of one group must be used
• Groups that are loaded with > 2 A should not be next to another;
example: 3 A-3 A-1 A-1 A-3 A-3 A-1 A-1 A instead of 3 A-3 A-3 A-3 A-1 A-1 A1 A-1 A
