F 3349
F 3349: 8-channel output module
safety-related, applicable up to SIL 3 according to IEC 61508
• resistive or inductive load up to 500 mA (at L+ 24 V or 48 V)
• lamp load up to 10 W
• with integrated safety shutdown
• with safe isolation, with line monitoring
Appertaining function block: HB-BLD-3 or HB-BLD-4
The module is automatically tested during operation. The main test routines are:
• Reading back of the output signals. The operating point of the 0-signal read back
is
≤ 6.5 V,
• Switching capability of the safety shutdown, cross-talking (walking-bit test),
• Line monitoring.
Nominal output voltage 24 V or 48 V, acc. to supply of L+ via cable plug,
500 mA, short-circuit-proof
Space requirement 4 SU
Operating data 5 VDC / 0.15 A,
24 VDC / 200 mA (via rear bus system)
24/48 VDC / 50 mA plus load (via cable plug)
