Bently 3500/60 and 3500/61 temperature modules

Bently 3500/60 and 3500/61 temperature modules

Module Core Overview

Bently Nevada's 3500/60 and 3500/61 temperature modules both have 6-channel temperature monitoring capabilities and are compatible with resistance temperature detectors (RTDs) and thermocouples (TCs) inputs. They can condition input signals and compare them with user programmable alarm thresholds. The core functions of the two are the same, the only difference being that the 3500/61 provides recorder outputs for each of the six channels, while the 3500/60 does not have this function.

The module needs to be set to RTD or TC measurement mode through the 3500 rack configuration software, providing multiple I/O module versions:

RTD/TC non isolated version: can be flexibly configured to receive only TC, only RTD, or a combination of both inputs;

TC Isolation Edition: Equipped with 250Vdc inter channel isolation capability, it can resist external interference.

In the Triple Modular Redundancy (TMR) configuration, three temperature monitors need to be installed adjacent to each other, and the system ensures operational accuracy through two voting mechanisms to avoid single point failures.

Key technical parameters

Measurement range: TC (Type J/K/T/E, Range reduction at high temperature for Type E); RTD (made of platinum/nickel/copper material, with some parts having a narrower range after external barriers, platinum RTD (α=0.00385) is an industry standard).

Output and accuracy: The front panel has OK/TX/RX/Bypass LEDs; RTD current source 925 ± 15 μ A (25 ℃); Temperature resolution of 1 ℃/℉, accuracy of ± 1-3 ℃ (depending on configuration), alarm accuracy of ± 0.13%, supporting warning (1-60 second step size of 1 second), danger (1-60 second step size of 0.5 seconds) delay.

Environment and size: working temperature 0-65 ℃ (with internal barriers), storage temperature -40-85 ℃; Monitor module 241.3 × 24.4 × 241.8mm (0.91kg), with slightly smaller I/O module size/weight, each occupying one full height slot.

Compliance and Ordering

Certification: Compliant with FCC, EMC (2014/30/EU), RoHS, IEC 62443 network security, up to SIL 2, certified for hazardous areas such as CSA/ATEX (with or without internal barriers).

Order: Both 3500/60 (without recorder) and 3500/61 (with recorder) are "Model - AA (I/O type) - BB (certified)", with accessories including terminal blocks, cables of different lengths (assembled/unassembled), and specialized spare parts.
