The Bently Nevada 3500/61-01-01 (133835-02) is a high-performance Temperature Monitor Isolated Input/Output (I/O) Module featuring internal terminations. Designed for the 3500 Machinery Protection System, this module provides continuous tracking of machinery temperature variables to protect critical assets such as turbines, compressors, and large pumps from thermal damage.
This specific isolated configuration is engineered to eliminate ground loop interference, ensuring reliable data flow and preventing false trips in demanding environments like petrochemical refineries and power plants. The 133835-02 serves as the specific hardware component for isolated I/O with internal termination resistors, facilitating direct thermocouple readings to the 3500 backplane.

Model Number: 3500/61-01-01
3500/61: Temperature Monitor Series Module.
01: Isolated Thermocouple I/O Module with Internal Terminations.
01: Agency Approval (CN, ATEX, and IECEx for Zone 2 and Class I, Division 2).
Hardware Part Number: 133835-02.
Hardware Inspection: Examine module pins for damage and verify that jumper settings on the monitor card match the intended sensor type.
I/O Module Installation (Rear): Align the 133835-02 with the rear chassis guides of the target slot. Seat the module firmly into the backplane and secure the thumb screws.
Monitor Module Installation (Front): Insert the 3500/61 Monitor card into the front slot directly opposite the I/O module. Secure with front panel screws.
Field Wiring: Connect sensor leads directly to the 133835-02 terminal blocks. For Thermocouples (TC), ensure correct polarity of positive and negative extension wires.
Configuration: Utilize the 3500 Configuration Software via the TDI port to define sensor types and set Alert/Danger setpoints before downloading to the rack.
Internal Terminations: This design allows field wiring to connect directly to the I/O module, eliminating the need for external terminal blocks and reducing cabinet space requirements.
Sensor Failure Protection: The module features built-in detection for broken wires. A sensor fault triggers a "Not OK" status, alerting the DCS while preventing accidental machine trips.
Input Constraints: This specific configuration (-01) is dedicated to isolated thermocouple inputs. It cannot mix RTD and thermocouple signals on the same I/O block.
What certifications does the -01 approval option provide?
It includes ATEX, IECEx, and CN certifications for use in Zone 2 and Class I, Division 2 hazardous environments.
Does this module require external resistors for termination?
No, the 133835-02 hardware contains internal termination resistors.
How is isolation achieved?
The module provides 500 VDC galvanic isolation to protect signal integrity from ground loop interference.
