The 133835-02 is a high-integrity Thermocouple (TC) Isolated I/O Module specifically designed for the Bently Nevada 3500/61 Machinery Monitoring System. This module provides six channels of precise temperature monitoring, acting as the critical rear interface for thermocouple signal acquisition. With its superior channel-to-channel isolation, it is engineered to deliver accurate thermal data even in the presence of heavy electrical interference and ground loops common in industrial power plants.
Model Number: 133835-02
Number of Channels: 6 Thermocouple Inputs
Isolation Rating: 250 Vdc (Channel-to-Channel)
Termination: Internal Screw Terminals (10-pin)
Wire Gauge Support: 0.2 to 2.1 $mm^2$ (24 to 14 AWG)
Operating Temp: -30°C to +65°C
Dimensions: 241.3 x 24.4 x 99.1 mm
Weight: 0.45 kg
Housing Material: Flame-retardant industrial plastic
Advanced Electrical Isolation: The 250 Vdc isolation between channels effectively eliminates ground loop issues, ensuring that a fault on one thermocouple does not compromise the entire monitoring group.
Six-Channel Capacity: Supports up to six independent temperature inputs, providing broad thermal coverage for bearing housings, windings, or exhaust gas paths.
Internal Termination Design: Features built-in screw terminals that simplify field wiring and eliminate the need for external termination blocks, reducing both cabinet space and installation costs.
Direct 3500/61 Integration: Purpose-built for the 3500/61 temperature monitor, ensuring "plug-and-play" compatibility and reliable data exchange with the rack's primary processor.
Rugged Safety Construction: Housed in high-temperature, flame-retardant industrial plastic to maintain mechanical and electrical stability in high-heat environments.
