Bently Nevada 3500/60-01-00 RTD Monitor

3500/60-01-00 Bently Nevada Temp Module

Product Introduction

The 3500/60-01-00 from Bently Nevada provides reliable temperature monitoring for critical machinery. This 3500/60 Temperature Module supports various RTD types and thermocouples. It is a non-isolated I/O module with internal terminations. Users can configure alert and danger setpoints through software. Furthermore, the module offers recorder outputs proportional to the full-scale value.

Technical Specifications

The 3500/60-01-00 accepts between one and six RTD or TC transducer signals. Each lead input has a 10 MΩ impedance. The nominal power consumption sits at 7 watts.

Supported RTD types include:

• 100Ω platinum RTD (alpha 0.00385): -200°C to +850°C

• 100Ω platinum RTD (alpha 0.00392): -200°C to +700°C

• 120Ω nickel RTD: -80°C to +260°C

• 10Ω copper RTD: -100°C to +260°C

Thermocouple (TC) ranges:

• Type E: -100°C to +1000°C

• Type J: -18°C to +760°C

• Type K: -18°C to +1370°C

• Type T: -160°C to +400°C

The RTD current source value equals 925 ±15 µA at 25°C. Additionally, recorder outputs range from +4 to +20 mA. Short circuits on recorder outputs do not affect monitor operation.

Alarm and Accuracy Details

Users can set alert and danger setpoints from 0 to 100% of full scale. Alarm accuracy stays within 0.13% of the desired value. Moreover, the module includes both under and over alarm setpoints.

Delay settings are programmable:

• Alert: 1 to 60 seconds in 1-second intervals

• Danger: 1 to 60 seconds in 0.5-second intervals

Accuracy with internal termination (non-isolated) : ±3°C at 25°C. For external termination in a standard rack, accuracy improves to ±1°C at 25°C. The cold junction compensation sensor provides ±1°C accuracy at 25°C.

Front Panel LEDs

The 3500/60-01-00 features three front panel LEDs. The OK LED indicates proper operation. The TX/RX LED shows communication with other 3500 rack modules. Finally, the Bypass LED lights when bypass mode is active.

Environmental Limits

Operating temperature ranges from -30°C to +65°C when used with internal or external termination I/O modules. For internal barrier I/O modules, the range sits at 0°C to +65°C. Storage temperature spans -40°C to +85°C.

Mechanical Dimensions

Monitor module dimensions:
241.3 mm (H) x 24.4 mm (W) x 241.8 mm (D)
Weight: 0.91 kg (2.0 lb)

I/O module dimensions (standard):
241.3 mm x 24.4 mm x 99.1 mm
Weight: 0.45 kg (1.0 lb)

I/O module dimensions (internal barrier):
241.3 mm x 24.4 mm x 163.1 mm
Weight: 0.46 kg (1.01 lb)

Rack Space Requirements

The monitor module occupies one full-height front slot. Correspondingly, the I/O module takes one full-height rear slot.

Installation Guidelines

First, ensure the 3500 rack is powered off before installation. Next, insert the 3500/60-01-00 into a full-height front slot. Then, mount the corresponding I/O module in the rear slot. Use the correct termination type based on your application. For external barriers, follow the specific temperature limits listed above. Finally, verify all connections before powering on the system.

Frequently Asked Questions (FAQ)

1. How many transducers can the 3500/60-01-00 handle?
This module accepts from one to six RTD or TC transducer signals simultaneously.

2. Can I use both RTDs and TCs on the same module?
Yes, the 3500/60 Temperature Module supports mixed configurations. However, each channel must be configured individually in software.

3. What happens if a recorder output short circuits?
Monitor operation remains unaffected by short circuits on recorder outputs. This feature ensures continuous temperature monitoring.

4. Do I need external barriers for all RTD types?
No. External barriers are optional for most RTDs. For platinum RTD (alpha 0.00392), barriers limit the range to -50°C to +260°C instead of the full -200°C to +700°C.

5. How accurate is the cold junction compensation for TCs?
The cold junction compensation sensor provides ±1°C accuracy at 25°C. This ensures reliable thermocouple measurements.
