Temperature Monitoring and Alarm Functions
The 3500/60 family accepts temperature signals from compatible resistance temperature detectors (RTDs) and thermocouples. The selected input configuration determines which sensor types the monitor can process. The monitor evaluates the measured values against configured alarm limits, allowing the monitoring system to identify temperature conditions that require attention.
I/O Configuration and Signal Compatibility
The family supports non-isolated I/O configurations for RTD, thermocouple, or mixed RTD and thermocouple inputs. An isolated I/O option is also documented for thermocouple applications, with 250 VDC channel-to-channel isolation. These options are not interchangeable assumptions for every assembly; verify the installed I/O module before selecting sensors or planning field wiring.
Difference Between the 3500/60 and 3500/61
The 3500/60 does not provide recorder outputs. This distinguishes it from the related 3500/61 family, which includes recorder output functionality. Confirm the required output signals and installed I/O configuration before selecting a monitor for an existing rack.
Frequently Asked Questions
Q: How many temperature channels does the 3500/60 support?
A: The 3500/60 family supports six temperature-monitoring channels. The exact configuration of the listed 133811-01 assembly still requires confirmation.
Q: Can the 3500/60 accept both RTD and thermocouple inputs?
A: The family supports RTD, thermocouple, and mixed-input configurations with non-isolated I/O. The isolated I/O option is for thermocouple inputs only. Verify the installed I/O module before connecting field sensors.
Q: Does the 3500/60 provide recorder outputs?
A: No. Recorder outputs are not provided by the 3500/60 family. Consider this distinction when checking replacement requirements or comparing it with the 3500/61.
