Product Description

The 3500/61-01-05 is a high-performance 6-channel temperature monitoring module part of the Bently Nevada 3500 Machinery Protection System. This specific configuration is distinguished by its integrated recorder outputs and Internal Safety Barriers, making it suitable for direct connection to sensors located in hazardous areas. It accepts both Resistance Temperature Detectors (RTDs) and Thermocouples (TCs), providing continuous surveillance of critical machinery temperatures in turbines, compressors, and large motors.

Technical Specifications

Specification Details

* Thermocouples: Type E, J, K, T, and S
Recorder Outputs Independent +4 to +20 mA DC proportional output for each of the 6 channels
Isolation 500 Vdc system isolation; non-isolated channel-to-channel
Power Consumption 9.0 Watts nominal
Dimensions 241.3 mm x 24.4 mm x 241.8 mm (Monitor)
Weight 0.91 kg 
Operating Temperature 0°C to +65°C 

System Integration

The 3500/61 differs from the standard 3500/60 by providing 4-20 mA recorder outputs for every channel, allowing for seamless integration with a DCS or PLC for trending and secondary control. The -05 internal barrier option simplifies installation in hazardous environments by eliminating the need for bulky external safety barriers, significantly reducing cabinet space requirements and wiring complexity.

Engineering FAQ

Q: Does the 3500/61-01-05 require a separate terminal block?
A: No. Because this version uses Internal Terminations, field wires are connected directly to the compression screw terminals on the back of the I/O module.
