Technical FAQs
1. What signal range does the 136499-01 module support?
It supports ±10 Vdc analog voltage signals for both input and output.
2. Can it handle only input signals?
No. It supports both input and output voltage signals.
3. Why does the module have external terminals?
External terminals simplify field wiring and maintenance activities.
4. Can this module operate outside a 3500 system?
No. It must be installed within a Bently Nevada 3500 rack.
5. Does the module provide electrical isolation?
No. It focuses on voltage I/O functionality, not isolation.
6. How does it communicate with the 3500 system?
Through the 3500 backplane interface.
7. Is it suitable for continuous industrial operation?
Yes. The module is designed for continuous duty.
8. Can it be used alongside vibration, temperature, or speed modules?
Yes. It is fully compatible with other 3500 modules.
9. What is the role of this module in machinery protection?
It provides voltage signals to support monitoring logic and coordinated protection actions.
10. How is it different from current-loop I/O modules?
It is designed specifically for voltage-based signals rather than +4 to +20 mA current loops.
