Bently Nevada 3500/33M 16-Channel Relay Module

Product Introduction

The Bently Nevada 3500/33M 16-Channel Relay Module is a high-performance, multi-channel relay output device designed for use within the 3500 Machinery Protection System. It provides programmable relay outputs that serve as interface points between monitoring modules and external control systems, enabling alarm, trip, and logic-based protection for rotating machinery.

Each relay can be independently configured for logic type, voting arrangement, and time delay, providing precise and reliable operation. The module’s robust design ensures long-term stability in harsh industrial environments, while advanced diagnostic functions provide continuous health monitoring of relay performance.

FAQ

1. What type of relays does the 3500/33M module use?
   The module uses industrial-grade Form C (SPDT) electromechanical relays designed for reliability in continuous operation.

2. Can each relay output be configured separately?
   Yes, all 16 channels can be configured individually for alarm or trip functions with different logic conditions.

3. What logic combinations are supported by the 3500/33M?
   The module supports AND, OR, 1-out-of-2, and 2-out-of-3 voting logic schemes for flexible protection strategies.

4. How is relay status indicated on the module?
   Each relay has LED indicators that show ON, ALARM, and TRIP conditions for real-time visual feedback.

5. Can the 3500/33M module be used in redundant rack systems?
   Yes, it is fully compatible with dual or redundant 3500 rack configurations for enhanced system reliability.

6. What is the maximum switching capacity of each relay contact?
   Each relay can switch up to 5 A at 30 VDC or 250 VAC for resistive loads.

7. Does the module support software-based relay testing?
   Yes, the Bently Nevada configuration software allows manual testing and simulation of relay operation.

8. How does the 3500/33M handle logic voting between multiple monitors?
   The module performs programmable logic voting, combining multiple input conditions before relay actuation.

9. Is there isolation between relays and system logic?
   Yes, galvanic isolation of 1500 V RMS exists between relay contacts and logic circuits to ensure signal integrity.

10. Can configuration data be retained after power loss?
    Yes, all configuration parameters are stored in non-volatile memory, preserving settings during power interruptions.
