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) relay contacts –
AgNi, gold-flashed
Contact ratings:
Maximum voltage: 250V ac/dc
Maximum current: 6 A ac/dc
Minimum current: 30 mA @ 24V dc
Maximum power: 1500VA, 200 W
Mechanical life: 50,000,000 operations
Electrical life: 100,000 at full resistive load
Feedback contact rating (Y1-Y2): 24V dc @ 0.5A
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
20 milliseconds maximum (if channel u-k fails, maximum response time is 200 milliseconds)
Status Indicators
3 green LED indicators:
Power ON
K1 energized
K2 energized
Input Requirements
Inputs from Primary Safety Device must each be capable of switching 30 to 250mA @ 13 to 28V 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
Operating Temperature
0° to +50°C (+32° to 122°F)
Supply Voltage and Current
A1-A2: 24V dc, +/-15%, 10% maximum ripple
