HIMA F 3334 / F3334 4 Fold Output Module

Key Features:

• Function: Safety-related 4-fold output module designed for handling resistive and inductive loads up to 2 A (48 W) and lamp connections up to 25 W.
• Safety Mechanisms:
  • Integrated safety shutdown
  • Safe isolation
  • Line monitoring
  • No output signal upon L- supply break
• Automatic Testing: Continuously tested during operation, including:
  • Reading back output signals with an operating point for 0 signal read back at ≤ 6.5 V
  • Switching capability and cross-talk detection (walking-bit test)
  • Line monitoring

Specifications:

• Outputs: 2 A, short circuit proof
• Internal Voltage Drop: Maximum 2 V at 2 A load
• Admissible Line Resistance: Maximum 3.6 Ohm
• Undervoltage Tripping: At ≤ 16 V
• Short Circuit Current: 2.6 to 5 A
• Line Break Current: 0.5 to 9.5 mA
• Output Leakage Current: Maximum 550 µA
• Output Voltage if Reset: Maximum 1.5 V
• Current Input WD: Maximum 30 mA
• Test Signal Duration: Maximum 250 µs
• Space Requirement: 4 TE
• Operating Data:
  • 5 V DC: 130 mA
  • 24 V DC: 130 mA in additional load

Additional Notes:

• Line Break Monitoring: Requires a minimum load of 10 mA. The signal "line break" can be used in user programs up to requirement class 3.
• Channel Operation: Only two channels may operate at the maximum load (2 A) simultaneously. If the load is up to 1 A, all channels can operate simultaneously.
• IO Rack Usage: Up to 10 output modules with nominal load can be used in one IO rack.
• Parallel Operation: Can be paralleled without the need for external diodes.
• Software Integration: Appertaining software building block HB-BLD-. For current version details, refer to the operating system description.
• Inrush Current Handling: Potential issues with certain 25 W lamp types due to high inrush current can be mitigated by setting a suppression time (1 to 50 ms) at the building block HB-BLD-. This extends the test duration by the set time if this input is occupied.

Planning Considerations:

• Ensure line break monitoring with a minimum load of 10 mA.
• For maximum load operation, limit to two channels concurrently; otherwise, all channels can run with loads up to 1 A each.
• In IO racks, restrict to a maximum of 10 output modules with nominal load.
• When using certain 25 W lamps, set inrush current suppression time to avoid faults.

This module provides robust and safe operation for managing various load types, with comprehensive safety features and automatic testing to ensure reliability and efficiency in critical applications.
