Safety Extension Module – Model EM-F-7G
Supply Protection Circuitry
Application Notes There are no adjustments and no user-serviceable parts. See page 6 for information regarding repair service.
Protected against transient voltages and reverse polarity
Output Configuration Four output channels:
Each channel is a series connection of two forced-guided (positive-guided) safety relay contacts –
AgSnO
2
Contact ratings:
Maximum voltage: 250V ac/dc
Maximum current: 6 A ac/dc (at specified operating temperature)
Minimum current: 30 mA @10V dc
Maximum power: 1500VA, 150 W
Mechanical life: 10,000,000 operations
Electrical life: 100,000 at full resistive load
Feedback contact rating (Y1-Y2): 250V ac/dc @ 3A
NOTE: Transient suppression is recommended when switching inductive loads. Install suppressors across
load. Never install suppressors across output contacts (see Warning, page 5).
Output Response Time 35 milliseconds typical
Status Indicators 3 green LED indicators:
Power ON
K1 energized
K2 energized
Input Requirements Input from Primary Safety Device must be capable of switching 40 to 100mA @ 13 to 27V ac/dc.
Construction Polycarbonate housing.
Mounting Mounts to standard 35 mm DIN-rail track.
Vibration Resistance 10 to 55Hz @ 0.35 mm displacement per IEC 68-2-6
