FAQ

1. What is the output switching mechanism used in the 2MLQ-TR2BA module?
   It uses sourcing transistor outputs (typically PNP configuration).

2. Does the module support hot-swapping during operation?
   No, this module does not support hot-swapping. Power down is required before replacement.

3. Can the output channels be configured independently?
   No, all channels are pre-defined for digital output and share common electrical characteristics.

4. Is the module compatible with Honeywell’s Safety Manager systems?
   Yes, it is designed to integrate with Honeywell’s Safety Manager and C300 systems.

5. What is the typical channel-to-channel isolation voltage?
   Typically rated at 500 VDC minimum between channels and system.

6. Does it support diagnostic feedback to the controller?
   Yes, it provides diagnostics for short-circuit, open load, and output status via the control system.

7. What is the recovery process after a channel protection trip?
   The module automatically resets the output after the fault is cleared.

8. Can this module be used in SIL-rated applications?
   Yes, the module is suitable for SIL2/SIL3 applications when used within an approved safety system.

9. What is the maximum total current the module can source simultaneously?
   Total output current should not exceed 8 A across all channels to prevent overheating.

10. How is firmware managed on this module?
    Firmware is fixed and not user-upgradable. Updates are handled through Honeywell service programs.
