BENTLY 3500/53 133396-01 Relay Module

The BENTLY 3500/53 133396-01 is another configuration of the 16‑channel relay output module within the Bently Nevada 3500 series. While functionally similar to the 133388‑01, this variant may incorporate different relay contact materials, higher current ratings, or special certifications (such as ATEX or IECEx) for use in hazardous areas or applications requiring enhanced switching capacity. It provides the same programmable logic and flexible alarm mapping essential for machinery protection.

Functional Overview

Like its counterpart, the 133396-01 receives alarm conditions from monitoring modules and activates its 16 relays accordingly. Each relay can be independently configured to respond to any combination of alarms (e.g., vibration, temperature, speed) with logic AND/OR functions. The module supports failsafe operation, relay latching, and time delays, allowing it to directly drive shutdown devices, alarms, or indicators.

Key Features

• 16 SPDT Relays: Independently programmable for maximum flexibility.

• Enhanced Contact Ratings: Depending on variant, may support up to 10 A at 250 VAC or 30 VDC.

• Hazardous Area Approvals: Optional certifications for use in Zone 2 or Class I, Div. 2 environments.

• Configurable Logic: Multiple alarm sources can be combined per relay.

• Visual Status: Front‑panel LEDs indicate each relay’s state.

• Hot‑Swappable: Replaceable under power (wiring must be de‑energized).

Technical Specifications

• Contact Arrangement: SPDT (Form C).

• Typical Ratings (133396-01 variant): 8 A @ 250 VAC, 8 A @ 30 VDC, 0.6 A @ 110 VDC.

• Isolation: 2500 VAC between coil and contacts.

• Response Time: < 20 ms typical.

• Power Consumption: 5 VDC @ 550 mA.

• Operating Temperature: -30°C to +70°C (depending on certification).

Applications

The 133396-01 is suitable for environments where higher contact loads or specific safety certifications are required. Common applications include direct control of motor starters, solenoid valves in safety circuits, and interfacing with emergency shutdown systems in offshore platforms or chemical plants. It offers the same integration with the 3500 rack and can be mixed with other relay modules to achieve the desired number of outputs.

Configuration and Integration

Configuration is performed via the 3500 System Configuration Software, similar to the 133388-01. The module’s unique part number may indicate pre‑set options (e.g., gold‑plated contacts for low‑level switching). It occupies a single slot in the rack and communicates via the internal bus. When replacing a module, the configuration is automatically downloaded from the RIM, ensuring consistent operation.

In summary, the BENTLY 3500/53 133396-01 relay module offers the same robust performance as the standard version but with enhancements tailored to specific industrial demands, providing reliable alarm output for critical machinery protection.
