The 3500/60 (Assembly Number 133843-01) is a high-precision 6-channel temperature monitoring module designed for the Bently Nevada 3500 Machinery Protection System. This module provides continuous thermal surveillance for critical machinery components such as bearings, stator windings, and lube oil systems. It is engineered to accept both Resistance Temperature Detectors (RTDs) and Thermocouples (TCs), converting these analog signals into digital data for real-time alarm processing and machinery protection.

| Signal Processing | 24-bit Analog-to-Digital (A/D) conversion for superior accuracy |
| Alarm Logic | Fully programmable Alert and Danger setpoints for all 6 channels |
| System Integration | Occupies one full-height slot in the 3500 series rack |
| Physical Dimensions | 24.13 cm (H) x 2.44 cm (W) x 24.18 cm (D) |
| Unit Weight | 0.86 kg |
| Operating Temperature | -30°C to +65°C (-22°F to +149°F) |
The 133843-01 is a cornerstone of proactive machinery maintenance. It features comprehensive self-diagnostics that continuously monitor the "OK" status of each transducer and the internal module circuitry. If a sensor failure or wire break is detected, the module alerts the operator via the 3500/22M Rack Interface, preventing false trips while ensuring the machine remains protected. Its robust design is optimized for the high-interference environments typical of power plants and refineries.
Q: Does the 3500/60 (133843-01) support Triple Modular Redundancy (TMR)?
A: Yes, when used in a TMR rack, these modules can be grouped in threes. The system utilizes a "2-out-of-3" voting logic to ensure that a single module failure does not compromise the protection of the machine or cause an unnecessary shutdown.
