Bently Nevada 3500/65-01-CN 3500/65 16-Channel Temperature Monitor

Description

The 3500/65-01-CN provides 16 channels of continuous temperature monitoring , accepting resistance temperature detector (RTD) and isolated tip thermocouple (TC) inputs. This temperature monitor conditions all field signals and evaluates them against user-programmable Alert and Danger alarm setpoints. Configured via the 3500 Rack Configuration Software, it handles isolated tip thermocouples, 3-wire RTDs, 4-wire RTDs, or combined TC/RTD arrangements. In Triple Modular Redundant (TMR) setups, monitors operate in adjacent groups of three, utilizing dual voting methodologies to maintain high operational integrity and eliminate single-point failures. The 3500/65-01-CN configuration specifically designates an I/O module type featuring internal terminations along with country-specific agency approvals.

Features

• Processes up to 16 channels of RTD or isolated tip TC inputs per module.
• Supports multiple sensor configurations, including 3-wire and 4-wire platinum, nickel, and copper RTDs alongside diverse TC options.
• Integrates software-programmable Alert and Danger alarm delays to optimize system event responses.
• Employs Front Panel LEDs (OK, TX/RX, Bypass) for rapid, direct verification of module, communication, and operational status.
• Enables Triple Modular Redundant (TMR) voting across adjacent hardware groups to enforce high fault tolerance.

Applications

• Machinery protection and continuous thermal tracking on industrial rotating assets.
• Bearing temperature supervision across large motors, pumps, and compressors.
• Exhaust gas temperature monitoring on industrial gas turbines.
• Winding temperature analysis for high-voltage generators.

Installation Guidelines

• Rack Mounting: Install the main module into a full-height front chassis slot and place the corresponding internal termination I/O module into the matching full-height rear chassis slot.
• TMR Configuration: When arranging a Triple Modular Redundant layout, you must place three temperature monitors in adjacent rack slots to support correct voting routines.
• Firmware Verification: Ensure that the 3500/22 transient data interface module firmware stands at Revision 1.50 or later, and matching configuration software is updated appropriately to support module additions.
• Wiring Separation: Do not attempt to hook up external termination blocks if an internal termination I/O module architecture is used.
