Simple and Reliable Temperature Monitoring
The Bently Nevada 3500/60-01-00 connects directly to RTD and thermocouple sensors. Each channel provides independent measurement. The module works with Type E, J, K, and T thermocouples.

Low Power Consumption
This temperature monitor uses only 7 watts nominal. It does not overload your rack power supply. The module stays cool during operation.

Clear Front Panel Indicators
Three LEDs show module status at a glance. The OK LED lights when the monitor works properly. The TX/RX LED blinks during communication. The Bypass LED indicates Bypass Mode is active.

Installation Guide
Rack Mounting Steps
Insert the monitor module into any front slot. Place the matching I/O module into the rear slot. Secure both modules with their locking tabs. No special tools are needed.

Wiring Connections
Connect RTD or TC wires to the I/O module terminals. Use shielded cables for best noise rejection. Keep wire runs as short as practical. Follow the termination label on the I/O module.

Software Configuration
Use 3500 Configuration Software to set up each channel. Select sensor type and measurement range. Program alarm setpoints and time delays. Save the configuration to the rack.

 Frequently Asked Questions (FAQ)
Question 1: How many sensors can the 3500/60-01-00 monitor at once?
This module accepts up to 6 RTD or thermocouple sensors. Each channel works independently.

Question 2: Can I mix RTD and TC sensors on the same module?
Yes, you can mix different sensor types. Configure each channel separately in the software.

Question 3: What happens if a recorder output shorts to ground?
The output has short circuit protection. The monitor continues normal operation without damage.

Question 4: How do I know if the module iscommunicating properly?
Watch the TX/RX LED on the front panel. A blinking light means active communication.
